Calculate Mass from Density Example Problem

Density is the amount of matter, or mass, per unit volume. This example problem shows how to calculate the mass of an object from a known density and volume. Simple Example (Metric Units) As an example of a simple problem, find the mass of a piece of metal that has a volume of 1.25  m3 and a density of 3.2 kg/m3. First, you should notice both the volume and the density use the volume of cubic meters. That makes the calculation easy. If the two units were not the same, youd need to convert one so they would be in agreement. Next, rearrange the formula for density to solve for mass. Density Mass à ·Ã‚  Volume Multiply both sides of the equation by volume to get: Density x Volume Mass or Mass Density x Volume Now, plug in the numbers to solve the problem: Mass 3.2 kg/m3 x 1.25 m3 If you see the units wont cancel out, then you know you did something wrong. If that happens, rearrange the terms until the problem works. In this example, cubic meters cancels out, leaving kilograms, which is a mass unit. Mass 4 kg Simple Example (English Units) Find the mass of a blob of water with a volume of 3 gallons. It seems easy enough. Most people memorize the density of water as 1. But thats in grams per cubic centimeters. Fortunately, its easy to look up the density of water in any unit. Density of Water 8.34 lb/gal So, the problem becomes: Mass 8.34 lb/gal x 3 gal Mass 25 lb Problem The density of gold is 19.3 grams per cubic centimeter. What is the mass of a bar of gold in kilograms that measures 6 inches x 4 inches x 2 inches? Solution Density is equal to the mass divided by the volume.D m/VwhereD densitym massV volumeWe have the density and enough information to find the volume in the problem. All that remains is to find the mass. Multiply both sides of this equation by the volume, V and get:m DVNow we need to find the volume of the gold bar. The density we have been given is in grams per cubic centimeter but the bar is measured in inches. First, we must convert the inch measurements to centimeters.Use the conversion factor of 1 inch 2.54 centimeters.6 inches 6 inches x 2.54 cm/1 inch 15.24 cm.4 inches 4 inches x 2.54 cm/1 inch 10.16 cm.2 inches 2 inches x 2.54 cm/1 inch 5.08 cm.Multiply all three of these numbers together to get the volume of the gold bar.V 15.24 cm x 10.16 cm x 5.08 cmV 786.58 cm3Place this into the formula above:m DVm 19.3 g/cm3 x 786.58 cm3m 14833.59 gramsThe answer we want is the mass of the gold bar in kilograms. There are 1000 grams in 1 kilogram, so:mass in kg mass in g x 1 kg/1000 gmass in kg 14833.59 g x 1 kg/1000 gmass in kg 14.83 kg. Answer The mass of the gold bar in kilograms measuring 6 inches x 4 inches x 2 inches is 14.83 kilograms. Tips for Success The biggest problem students make when solving for mass is not setting up the equation correctly. Remember, mass equals density multiplied by volume. This way, the units for volume cancel out, leaving the units for mass.Be sure the units used for volume and density work together. In this example, the mixed metric and English units were intentionally used to show how to convert between units.Volume units, in particular, can be tricky. Remember, when you determine volume, you need to apply the correct formula. Summary of Density Formulas Remember, you can arrange one formula to solve for mass, density, or volume. Here are the three equations to use: Mass Density x VolumeDensity Mass  Ãƒ · VolumeVolume Mass  Ãƒ ·Ã‚  Density Learn More For more example problems, use the Worked Chemistry Problems.

Without Connection to Others There Is No Me - 1863 Words

Prompt: Without connection to others there is no me. In a society which inherently seeks to categorise individuals, it is paramount that each person finds their genuine place in the world. The most powerful influences that impact on an individual’s sense of belonging include identity and heritage. It is a part of humanity which makes us desire to want to belong to a social, religious or even racial group which ultimately forms the person we become. Renowned author Carlson McCullers reflects these ideas. â€Å"I think the idea of wanting to belong haunts every child. And not only children. I think it is the primary question. Who am I? What am I? And where do I belong?†It is of grave importance that we understand we are simply mere shadows of†¦show more content†¦These connections ideally provide love, protection, security and the opportunity to discover our values, attitudes, and beliefs that help to define us from the time of our birth. In McCullers ‘The Member of the Wedding’, Frankie latches onto t he idea that she will be someone of importance if she pursues a life with her older brother Jarvis and his wife to be Janice. The coming of the wedding gives her something to latch onto, and she becomes actively involved with the wedding, convincing herself of the false reality of â€Å"the future ahead when the three of them would be together in all the many distant places†. Ultimately Frankie has been unable to establish a persona until the coming of her brother’s wedding where she has latched onto the idea of being a part of it. Nevertheless, this sense of belonging to the bride and groom and the wedding itself, as strange and superficial as it may seem, makes her feel as if she suddenly has a purpose in life and allows her to understand who she is: â€Å"they are the we of me†. These examples clearly reveal that without connections, an individual is often incomplete, and stuck with the notion that they are isolated from the world entirely. Author Orson Scott has echoed these sentiments in saying, â€Å"Perhaps its impossible to have a true identity without becoming what you pretend to be.† In addition, if an individual is incapable of connecting with others, they will lose our senseShow MoreRelatedWithout Connection to Others There Is No Me Member of the Wedding1433 Words   |  6 Pagesâ€Å"Nothing of me is original.

The study is based on the critical analysis of an Organizational Website. Singapore Airlines has been selected as the case study for this study. Singapore Airlines has been selected because it is a very popular website and is used frequently by many customers for purchasing their air tickets. Moreover, since it is an e-commerce website, designing the website accurately so as to make it user friendly is also important. In order to evaluate the website critically, a detailed analysis of the design of the website along with the icons and the color combination used in designing the website will be done. It is based on the analysis, certain recommendations will be made to improve the design of the website to certain extent. Discussion: Overview of the website: The Home Page of the Singapore Airline website directs the visitors of making or managing their flight booking. The options are easily visible and clear and are very user friendly. After filling the requisite areas, the page directs to the payment options, from where the customers can select the desired option and can purchase the flight ticket. The website is also clustered with the information about the organization and is helpful for gaining any kind of details about the organization. The website is specifically arranged with key words that open up to the requisite pages (Singaporeair.com 2017). Fig: Home Page of Singapore Airlines (Source: Singaporeair.com 2017) 1. Shortcuts: Structure of a website affects the success of an organization. It has been known that although not evident, the color and the typography used to design a website holds great importance. It depends of the color and the structure that how well the website can be read by the visitors. An important quote by Steve Jobs can be cited here, Design is not just what it looks like and feels like. Design is how it works. Keeping this perspective into consideration, it can be said that the icons are much visible and are user friendly (Webstyleguide.com 2017). Blue and white colors have been used for designing the website. The selected color soothing to ones eyes that it is effective to draw the attention of the visitors (Singaporeair.com 2017). 2.

Macbeth Essays (451 words) - Characters In Macbeth,

Macbeth Macbeth, written by William Shakespeare, is one of literature's greatest tragedies. Shakespeare wrote the play in 1605 and based it on events that took place in eleventh century Scotland. It is one of his best plays and is still studied around the world. The play focuses on the character Macbeth. During the course of the play, Macbeth changes from noble, to guilt-ridden, and finally to evil. Macbeth shows his nobility in the early scenes of the play. After a fierce battle, one of King Duncan's captains tells the king of Macbeth's great fighting skill and valor in killing one of the king's enemies, Macdonwald (Act I, Scene 2, Lines 16-24). This shows Macbeth's bravery. Later, King Duncan states, "What he hath lost, noble Macbeth hath won."(Act I, Scene 2, Line 67). King Duncan is referring to the title, Thane of Cawdor, which he gives to Macbeth as a result of the previous holder's treachery. Macbeth asks why he has been dressed in borrowed robes (Act I, Scene 3, Lines 109-110). With that statement, Macbeth shows that he does not desire another person's position. Macbeth's guilt-ridden conscience begins to appear after his murder of Duncan. Shortly after, Macbeth finds that he cannot say amen after one of the king's guards cried, "God bless us!" (Act II, Scene 2, Lines 26-29). Macbeth feels he has done an unforgivable crime and can no longer refer to God. Not much later, Macbeth claims to have heard a voice cry, "Sleep no more!"(Act II, Scene 2, Line 34). Macbeth's conscience will no longer allow him to sleep peacefully. He later states, "Will all great Neptune's ocean wash this blood clean from my hand? No..."(Act II, Scene 2, Lines 59-60). Macbeth feels that nothing could clear his guilty conscience. In the latter stages of the play, Macbeth becomes evil. Macbeth fells threatened by Banquo and employs murderers to kill his former friend (Act III, Scene 1). Macbeth has become evil enough to murder his best friend. Later, Macbeth murders again. This time, he kills Macduff's family because he thinks Macduff is a traitor to him (Act IV, Scene 2). Again, this shows his evil in that he murdered totally innocent people. After learning of his wife's suicide, he emotionlessly states, "She should have died hereafter," which means he felt her death was inevitable (Act V, Scene 5, Line 17). This lack of feeling or sorrow for his dead wife truly shows how evil has finally taken over Macbeth. Macbeth's character changes from noble, to guilt-ridden, and finally to evil during the play. In the beginning of the tragedy, Macbeth is a noble person. After killing Duncan, Macbeth quickly becomes guilt-ridden. Macbeth's guilt finally turns to evil as he murders and shows no remorse of his actions. This evil finally results in his gruesome death.
