DENSITYWhat is the density of a metal that has a mass of 20.3 g and a volume of 2.8 cm3?

D = m D = 20.3 g D = 7.25 g/cm3

V 2.8 cm3

DENSITYBilly wants to find the density of a rock. He puts 10 mL of water in a graduated cylinder. He adds the rock and the water line rises to 15.3 ml. He then finds the mass of the rock is 12.4 g. What is the density of the rock?

V = 15.3 mL – 10 mL V = 5.3 cm3

D = m D = 12.4 g D = 2.3 g/cm3

V 5.3 cm3
