Example 1:
While doing dishes, Dominick drops a 3.0 gram platinum wedding band into the dishwater. The sink
water rises a volume of 0.0014 mL of water. What is the density of the platinum band?
Example 2:
Water has a density of 1.0 g/cm3 when it is at 4 C. As it begins to freeze the density of water drops to
0.92 g/cm3 when it turns to ice. Is it safe to put a bottle of water in the freezer if the bottle contains 500
g of water in a container that is 530 mL big?
Example 3:
Rick from Pawn Stars has just agreed to buy a gold bracelet from a customer. He measures the mass of
the bracelet and finds that it is 130 g. He then places it in a cup of water measures the water
displacement to be 8.5 mL. If the density of gold is 19.3 g/mL, did Rick make a good purchase or did he
buy a fake?
