DENSITY AP PRACTICE Zumdahl 7 th Edition

2
Sample One A material will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0 g/mL, will a block of material having a volume of 1.2x10 4 in 3 and weighing 350 lb float or sink when placed in a reservoir of water? 2

3
Sample Two For a material to float on the surface of water, the material must have a density less than that of water (1.0 g/mL) and must not react with the water or dissolve in it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g. Will this ball float or sink when placed in water? (Note: volume of a sphere = ¾ π r 3 ) 3

4
Sample Three A star is estimated to have a mass of 2x10 36 kg. Assuming it to be a sphere of average radius 7x10 5 km, calculate the average density of the star in units of grams per cubic centimeter. (Note: volume of a sphere = ¾ π r 3 ) 3

5
Sample Four A rectangular block has dimensions 2.9cm x 3.5cm x 10.0cm. The mass of the block is 615.0g. What are the volume and density of the block? 1

6
Sample Five A sample containing 33.45g of metal pellets is poured into a graduated cylinder initially containing 12.7 mL of water, causing the water level to rise to 21.6 mL. Calculate the density of the metal. 1

7
Sample Six The density of pure silver is 10.5 g/cm 3 at 20˚C. If 5.25g of pure silver pellets are added to a graduated cylinder containing 11.2 mL of water, to what volume level will the water in the cylinder rise? 2

8
Challenge The density of osmium (the densest metal) is 22.57g/cm 3. If a 1.00kg rectangular block of osmium has two dimensions of 4.00cm and 4.00cm, calculate the third dimension of the block. 4
