Volume and Density
Density Problem Set
Name___________________________ Period__________
Solve the following problems. Show all work, and report your answer to the correct number of significant figures. Be sure to report the proper units.
: Densities of common substances at room temperature (g/cm3) Air 0.0013 Water 1.00 Aluminum 2.70 Gold 19.3
1. An object has a mass of 57.7 g and occupies a volume of 21.65 cm3, what is its density?
2. An object whose density is 1.98 x 103 kg/m3 has a mass of 35.4 g. How many cubic centimeters does the object occupy?
3. A cylinder has a radius of 12.0 cm. It has a density of 15.2 g/cm3 and a mass of 100 g. What is the height of the cylinder? (Hint: volume of a cylinder can be calculated by r2h)
4. A friend shows you a gift she has received- a gold ring. In the laboratory, you find its mass to be 58.21g and its volume to be 3.64cm3. Calculate the density of the ring. Is it really pure gold? Why or why not?
5. Chloroform is a liquid with a sticky sweet odor that was once used as an surgical anesthetic. If the density of chloroform is
1.49g/cm3, what is the volume of 25g of chloroform?
6. The density of copper is 8.96g/cm3. If a rectangular sheet of copper is 10.3cm wide, 46.1cm long, and 0.14cm thick, what is the mass of the copper?
7. Mercury is a liquid at room temperature with a density of
13.6g/cm3. Would a bar of aluminum float or sink in a pool of liquid mercury? Explain your answer.
