Some Density Problems

Students at the Help! Session last night requested some additional density problems. Here is what I found;

Density Question #1:

What is the volume of a 898 kilogram piece of iron metal (density is 7.75 g mL-1)? How long would a piece of iron have to be if the base is 1.50 cm2?

Density Question #2:

A packing material has a density of 12.8 kg m-3. How many grams of the material are needed to fill a volume of 3.00 ft3 ?

Density Question #3:

Which of the following items would be the heaviest?

a) a 100 pound bag of dog food;

b) a 15 gallon plastic container of water (assume the container's mass is negligible);

c) a 3.0 L container of mercury (density = 13.6 g mL-1).

Density Question #4:

Mercury is shipped in containers holding 76 pounds of mercury. Whould such a container fit into a wooden box which has inside dimensions of 8.0 inches by 4.0 inches by 4.0 inches?
