How much heat energy is required to convert 76.9 g of solid ethanol at –114.5 °C to gasesous ethanol at 150.7 °C? The molar heat of fusion of ethanol is 4.60 kJ/mol, and its molar heat of vaporization is 38.56 kJ/mol. Ethanol has a normal melting point of –114.5 °C and a normal boiling point of 78.4 °C. The specific heat capacity of liquid ethanol is 2.45J/g · °C, and that of gaseous ethanol is 1.43J/g · °C. kJ
