Name: ___________________________ Date: ____________ Block: _______ Density Problem Set Equation: D m V 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? Name: ___________________________ Date: ____________ Block: _______ Complete the following problems on a separate sheet of paper. Show you work to receive full credit. 1. The planet Saturn has a mass of 5.69 x 1026 kg and a volume of 8.01 x 1023 m3. a. What is the density of Saturn? b. Would Saturn Sink or Float if you could place it in a gigantic bathtub filled with water? 2. Diamond has a density of 3.520 g/cm3. During a class lab, a diamond drops out of a student’s necklace and lands in a graduated cylinder filled with 5 ml of water. When the diamond settles on the bottom, the water level has risen to 5.05 ml. What is the mass of the diamond? 3. A 1.9 kg piece of wood from a sunken pirate ship has a volume of 0.00216 m3. Will the piece of wood float to the surface or stay sunken. The density of water is 1000 kg/m3. 4. An iron nail has a density of 7.8 g/cm3 and a mass of 16 grams. What is the volume of the nail?
