Calculating Density
Follow these steps in order to solve the following problems
*you will be graded on showing the work as well as the answer*
* the points that will be awarded for each problem are listed off to the side*

Sample A metal bar has a mass of 10 grams and a volume of 5 mL. Calculate the density
Problem of that metal bar.

1 pt Step #1: Write out the formula. D = M ÷ V

2 pts Step #2: Write out the numbers that D = ? You have been given M = 10 grams In the problem V = 5 milliliter

2 pts Step #3: Replace the letters in the equation D = 10 grams / 5 milliliter With the numbers that you Know from the problem.

1 pt Step #4: Solve the problem and write your answer D = 2 grams/milliliter You may abbreviate the units D = 2 g/mL

**Notice that you are only awarded 1 point for the answer and 4 points for the other work. This needs to be done so we can see where mistakes are made in the event that you get the wrong answer.**

Solve the following problems in your composition book. Title the page “Calculating Density” Show ALL steps like the sample above!! Place this sheet in the center of your folder.

1. If 96.5 grams of gold has a volume of 5 cm3 , what is the density of that gold?

2. If 96.5 grams of aluminum has a volume of 35 cm3 , what is the density of the aluminum?

3. If the volume of a diamond is 0.5 cm3 and its mass is 7 grams, what is the density of that diamond?

4. What is the density of a plastic bracelet that has a volume of 4 cm3 and a mass of 3.12 grams?

5. What is the

Solution: Grams Essay

using different expressions. Weight in volume: Prepare 2 liters 0.85% sodium chloride With 1% defined as 1 gram per 100 ml, 0.85% is 0.85 grams per 100 ml. Since two liters is 20x the volume of 100 ml, we need 20 x 0.85 grams which is 17 grams NaCl. For this quantity we can use a top loading balance or even a trip balance. A typical electronic balance is accurate to one hundredth of a gram, which is sufficiently accurate for weighing out 17 grams. First we "tare" the instrument by placing…

Coke Density Lab

In this lab, we explored density, which is defined as “the degree of compactness in a substance.” To calculate density, one would take the mass of an object and divide that number by the object’s volume. The higher the number after doing the calculation, the higher the density, meaning an object with a high density would be considered more compact or concentrated than an object with a lower density. This lab was designed to investigate the differences in densities between regular Coke and Diet Coke…

Essay on Whap: Volume and Density

measure mass like grams, kilograms, pounds, or ounces. “Volume is the amount of space an object occupies”(Measuring Density Lab 1) Volume can also be measured in multiple units like liters, meters cubed, gallons, quarts, cubic centimeters, and cubic inches. Mass and volume are both needed to find density. Density is the ratio of mass to the volume of a specimen. The equation for finding density is P (density)=M (mass)/V (volume) so P=M/V (1.1) Density equals mass divided by volume Sample Problem…

appropriate units, grams (g) and practice using triple beam balance Measure the mass of 1 mL of water (it will be 1 gram) Practice weighing techniques on a balance. Mass is NOT affected by the force of gravity. Regarding mass, location in universe does not affect it. Ex. If an object's mass is 60g on Earth, the mass will also be 60g on Moon. Compare and contrast mass vs. weight. Use a spring scale to model how weight is affected by the force or pull of gravity. VOLUME: amount of space that…
