HONS CHEM Name: 8/30/18 ___________________________________________________________ Density 1) A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density? 2) Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury. 3) A piece of metal with a mass of 147g is placed in a 50-mL graduated cylinder. The water level rises from 22 mL to 41 mL. What is the density of the metal? 4) Silver has a density of 10.5 grams/cm3 and gold has a density of 19.3 g/cm3. Which would have the greater mass, 5.0 cm3 of silver or 5cm3 of gold? 5) 5.0 mL of ethanol has a mass of 3.9 g, and 5.0 mL of benzene has a mass of 44.0 g. Which liquid is denser? Density Calculations: Volume by displacement 1. A piece of metal with a mass of 147g is placed in a 50-mL graduated cylinder. The water level rises from 22 mL to 41 mL. What is the density of the metal? 2. A Nickel nugget with mass 187 g is placed in a 100 mL graduated cylinder. The water level rises from 75.0 mL to 96.0 mL. What is the density of Nickel? 3. A sample of aluminum is placed in a 25 mL graduated cylinder containing 10.5 mL of water. The level of the water rises to 13.5 mL. The density of aluminum is 2.7 g/mL. What is the mass of the aluminum sample?
