Iron has a density of 7.86 g/cm° (1 cm° = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 3.62 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. Express your answer to three significant figures.

3 Iron has a density of 7.86 g/cm³ (1 cm' = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.49 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 cm = 1 mL) before calculating the volume for the piece of iron. Express your answer to three significant figures.
