Under atmospheric pressure iron melts at 1530 ºC, and the latent heat of fusion is 1.49 × 104 J / mole. At the melting point, the density of the solid is phase is 7.80 g / cm3, and that of the liquid phase is 7.06 g / cm3. The atomic mass for iron is 55.8
(a) What are the molar volumes (in m3) for iron in the solid and liquid phases at the melting point?
