Density Rewiew(turn to page 24 in your textbook)
1. What is Density?
2. Why is Density important to science?
3. How do you calculate Density?
4. What are the 2 ways you can solve for volume? (hint your units are either cm3 or ml)
Density Problems
5. Look at the picture of the layers above.
a. which color is the most dense liquid?
b. which color is the least dense liquid?
Solve the following Problems:
Mass m
Density = -------------- or D = -------
Volume v
Use the density formula to solve the following problems:
| 6. Calculate the density of a material that has a mass of 52 g and a volume of 13 cm3. |
| 7. A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock is 22 cm3, and the mass in 40 g. What is the density of the rock? |
| 8. If 30 g of a liquid occupy a space of 35 ml, what is the density of the liquid in g/cm3? |
| 9. The density of silver is 10 g/cm3. If a sample of pure silver has a volume of 12 cm3, what would the mass? | |||
| 10. How many grams of tin would occupy 5.5 L, if it has a density of 7.5 g/cm3?
| |||
11. What is the mass of a 35 cm3 sample of pure silicon with a density of 2 g/cm3?
