Density #6
1. You are given equal masses of lead, aluminum, platinum, and brass. Arrange these masses in order of increasing volume.
2. You are given equal volumes of the same metals as in question #1. Arrange them in order of increasing mass.
3. Calculate the volume of 1 gram of each of the following: balsa wood, aluminum and oxygen.
4. Calculate the mass of 5 mL of platinum and 10 L of oxygen.
5. Calculate the mass of a liquid with a density of 3.2 g/mL and a volume of 25 mL.
6. A room is 5 m long, 4 m wide, and 3 m high. What is the mass of the air it contains?
7. Calculate the mass of a cube of aluminum with the following dimensions: length=3 cm, width=2 cm, height=4 cm.
8. An irregular object with a mass of 18 kg displaces 2.5 L of water when placed in a large overflow container. Calculate the density of the object.
9. Calculate the density of a 500 g rectangular block with the following dimensions: length=8 cm, width=6 cm, height=5 cm.
10. Calculate the mass of a solid metal cylinder with a density of 2.6 g/cm3, a diameter of 1.8 cm, and a length of 4 cm.
11. A graduated cylinder has a mass of 80 g when empty. When 20 mL of water is added, the graduated cylinder has a mass of 100 g. If a stone is added to the graduated cylinder, the water level rises to 45 mL and the total mass is now 156 g. What is the density of the stone?
12. If gold cost $500/oz, how many mm on a side does a $10 000 cube of gold measure?
13. One gram of gold can be beaten out into a foil 1 m2 in area. (Thus an ounce of gold can yield 300 ft2 of foil.) How thick is such a foil?
