Ethanol, C_(2)H_(6)O, is an organic compound commonly used as a solvent and fuel additive. It has a melting point of -114\deg C and a boiling point of 78.0\deg C. Its enthalpy of vaporization is 38.6k(J)/(m)ol, and its enthalpy of fusion is 4.90k(J)/(m)ol. The specific heats of solid and liquid ethanol are 0.97(J)/(g)*K and 2.3(J)/(g)*K, respectively. How much heat is required to convert 75.0 g of ethanol at -130\deg C to the vapor phase at 78.0\deg C ?
