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 4.84 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.

The volume of Iron (in cm^3) = 4840/7.86 = 615.78 cm^3.
1 cm^3 = 1 mL and there are 1000 mL in 1 dL

So to convert from cm^3 to dL, we just have to divide by a 1000

615.78/1000 = 0.61578 dL
