1)Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder has a mass of 306.0 g. From this information, calculate the density of mercury. 2) A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block has a mass of 1587 g. From this information, calculate the density of lead. 3) 28.5 g of iron shot is with a volume of 3.6mL is poured into a pile. From this information, calculate the density of iron. 4) Liquid A has a density of 5 g/mL, Liquid B has a density of 3 g/mL, Liquid C has a density of 7 g/mL, Liquid D had 1 g/mL. Knowing this if these liquids were mixed, list the order of the layers they would settle in from top to bottom.
