Iron has a density of 7.86 g/cm3 . Calculate the volume (in dL ) of a piece of iron having a mass of 4.89 kg . Note that the density is provided in different units of volume and mass than the desired units of volume ( dL ) and the given units of mass ( kg ). You will need to express the density in kg/dL ( 1 cm3 = 1 mL ) before calculating the volume for the piece of iron.
