Iron has a density of 7.86 g/cm3 7.86 g / c m 3 ( 1 cm3=1 mL 1 c m 3 = 1 m L ). Calculate the volume (in dL d L ) of a piece of iron having a mass of 3.33 kg k g . Note that the density is provided in different units of volume and mass than the desired units of volume ( dL d L ) and the given units of mass ( kg k g ). You will need to express the density in kg/dL k g / d L ( 1 cm3 = 1 mL 1 c m 3 = 1 m L ) before calculating the volume for the piece of iron.
