The density of magnesium is 1.7 g/cm3 , and the density of iron is 7.9 g/cm3 . Consider a block of iron with a mass of 819g. What is the mass of a block of magnesium that has the same volume as the block of iron?
Iron has a density of 7.86 g/cm37.86 g/cm3 (1 cm3=1 mL1 cm3=1 mL). Calculate the volume (in dLdL) of a piece of iron having a mass of 4.32 kgkg . Note that the density is provided in different units of volume and mass than the desired units of volume (dLdL) and the given units of mass (kgkg). You will need to express the density in kg/dLkg/dL (1 cm3 = 1 mL1 cm3 = 1 mL) before calculating the volume for the piece of iron.
Express your answer to three significant figures.
