1. Practice Density, Mass and Volume Questions

2. 1. A piece of tin has a mass of 16. 52 g and a volume of 2. 26 cm3
1. A piece of tin has a mass of g and a volume of 2.26 cm3. What is the density of tin?
Given
Mass= 16.53g Volume 2.26cm3
Unknown
D=?
Equation
D=M/V
Sub and Solve
D=16.53g/2.26cm3
D= 7.3g/cm3
Sentence
The piece of tin that has a mass of 16.52g has a density of 7.3g/cm3

3. 2. A man has a 50.0 cm3 bottle completely filled with 163 g of a slimy green liquid. What is the density of the liquid?
Given
V=50.0cm3 M=163g
Unknown
D=?
Equation
D=M/V
Sub and Solve
D=163g/50.0cm3
D=3.26g/cm3
Sentence
The slimy green liquid has a density 3.3g/cm3

4. 3. A sealed 2500 cm3 flask is full to capacity with 0
3. A sealed 2500 cm3 flask is full to capacity with 0.36 g of a substance. Determine the density of the substance. Guess if the substance is a gas, a liquid, or a solid.
Answer g/cm3
The sealed flask is a gas

5. 5. The density of pine is generally about 0. 5 g/cm3
5. The density of pine is generally about 0.5 g/cm3. What is the mass of a 800 cm3 piece of pine?
Given
D= 0.5g/cm3
V= 800cm3
Unknown
M=?
Equation
M=D x V
Sub and Solve
M =0.5g/cm3 X 800cm3
M=400g
Sentence
The mass of the pine is 400g

6. 6. What is the volume of 325 g of metal with a density of 9.0 g/cm3?
Given
M= 325g
D=9.0g/cm3
Unknown
V=?
Equation
V=M/D
Sub and Solve
V= 325g/9.0g/cm3
V=36.1cm3
Sentence
The volume of the metal is 36.1cm3

7. 7. Diamonds have a density of 3. 5 g/cm3
7. Diamonds have a density of 3.5 g/cm3. How big is a diamond that has a mass of 0.10 g?
Answer – 0.029cm3

8. 9. A graduated cylinder is filled with water to a level of 40. 0 mL
9. A graduated cylinder is filled with water to a level of 40.0 mL. When a piece of copper is lowered into the cylinder, the water level rises to 63.4 mL. Find the volume of the copper sample. If the density of the copper is 8.9 g/cm3, what is its mass?
