Mr. Wood
Please solve the following problems on separate sheets of paper. Show complete solutions and all
units.
1. A gold-colored ring has a mass of 18.9 grams and a volume of 1.12 mL. Is the ring pure gold? (The
density of gold is 19.3 g/mL.)
2. Pumice is volcanic rock that contains many trapped air bubbles. A 225 gram sample occupied 236.6
mL. What is the density of pumice? Will pumice float on water? (The density of water is 1.0 g/mL.)
3. What volume would a 0.871 gram sample of air occupy if the density of air is 1.29 g/L?
4. A cup of sugar has a volume of 237 mL. What is the mass of the cup of sugar if the density is 1.59
g/mL?
5. What is the thickness of a piece of wax paper (density = .40 g/cm3) that measures 3.0 cm by 5.0 cm
and has a mass of .10 grams.
6. How long does it take to travel 6.85km at a speed of 3.8 m/s?
7. If a car travels at 4.8 m/s for 29 minutes, then travels at 21.8 m/s for 7 hours and 12 minutes, how far
does it travel?
8. A bicyclist travels at 3.2 m/s for 2.5 Km, and then travels at 1.8 m/s for 1.5 Km, how many minutes
was the bike ride? What was the rider’s average speed?
9. What is the pressure exerted on the floor by a 1.1 ton elephant standing on a 4 ft by 8 ft sheet of
plywood that is resting flat on the floor?
10. How much do I weigh if I cause a total of four square inches of rubber (2 per tire)to contact the
ground when I sit on a 45 lb bicycle with a pressure of 60 psi in each tire?
11. How much pressure will you feel on the bottoms of your feet if you weigh 135 lbs and your shoes
each have an area of10 in2? How will this change if you are riding in an elevator that is moving
downward with a force of 50 pounds?
12. What is the pressure exerted on the floor by a cube measuring 6 inches on a side, with a density of
65 lbs. per cubic foot?
13. If 20 gits equal 1 erb, and 1 futz equals 2 hews, and 10 erbs equal 1 futz, how many gits equal 5
hews? (ratio problem)
