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 4.54kg . 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 before calculating the volume for the piece of iron.

Answer 1

we are given with a density of iron equal to 7.86 g/cm3 and is asked for the volume of the piece when there is a mass of 4.54 kg. In this case, we convert g/cm3 to kg/dL first. 1 g/cm3 is equal to 0.1 kg/dL that is the density is equal to 0.786 kg/dL. A mass if 4.54 kg is equivalent to 5.78 dL
