What is its density? (HINT: find the volume of the block first) D= M= V= 3) Mercury metal is poured into a graduated cylinder that holds exactly 22 ml. The mercury used to fill the cylinder weighs 308 g. From this information, calculate the density of mercury. D= M= V= 4) 5) What is the mass of the gas that exactly fills a 200.0 ml container? The density of the gas is 5 g/ml. D= M= V= m d v A rectangular block of metal weighs 480 g. The dimensions of the block are 8 cm by 5 cm by 4 cm. From this data, what is the density of copper? (HINT: find the volume of a block first) D= M= V= 6) What volume of silver will weigh exactly 2500 g. The density of silver is 10 g/cm3. D= M= V= 7) 8) 9) Find the mass of 250 ml of water. The density of water is 1 g/ml. D= M= V= A block of metal has dimensions of 2 cm by 5 cm by 6 cm. The block weighs 780 g. From this information, calculate the density. D= M= V= 28 g of iron shot is added to a graduated cylinder containing 40 ml of water. The water level rises to the 44 ml mark. From this information, calculate the density of iron. D= M= V= `
