1. If a penny weighs 2.50 grams, what would be the value in dollars of 5.00 metric tons? (1 metric ton =
2000 grams)
2. If a penny weighs 2.50 grams, what would be the volume of 1 penny (density of a penny is 8.933 g/ mL)
3. What will be the volume in liters of 16.0 grams of oxygen if 1 mL of oxygen weighs 0.00143 grams?
4. The density of sodium hydroxide solution is 1.1589 g/mL. What is the mass of 550 mL of this solution?
5. How large a container, in milliliters, would you need to hold 7.2 kg of gasoline? (the density of gasoline
is 0.68 g/mL)
6. Light travels at a speed of 3.00 X 1010 cm/s. What is that speed in km/hr?
7. Convert 0.72 g/mL to grams per liter.
8. Determine the mass of 125 mL of a gas whose density is 1.43 g/L
9. A space scientist landed on Mars and stumbled upon a chemical stockroom. He asked the Martian
attendant for 28 grams of formaldehyde to renew the fuel cell for his radio transmitter. The Martian
replied, “How many zooms of formaldehyde is that?”
10. The mass units on Mars were zings, zooms and warps. If 5 zings = 4 grams, 2 warps = 3 zings, and 9
zooms = 5 warps, how many zooms did the space scientist request?
