Question

Iron has a density of 7.86 g/cm3 (1 cm3=1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 3.88 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.

Answer 1

The volume of iron is obtained from the density formula (density= mass/ volume) given the density and mass. In this case, 3,880 grams of iron and a density of 7.86 g/ml are given. The volume obtained from formula is 493.64 ml or 4.94 dL.
