How much heat energy is required to convert 56.4 g of solid ethanol at −114.5°C to gasesous ethanol at 191.3°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.
