How much energy in kilojoules is released when 28.9g of ethanol (C₂H₆O) vapor at 92^oC is cooled to -19.0^oC?

Ethanol has: melting point = -114.1^oC, boiling point = 78.3^oC enthalpy of vaporization (delta H_vap) = 38.56 kJ/mol enthalpy of fusion (delta H_fus) = 4.93kJ/mol The molar heat capacity is 112.3J/(Kmol) for the liquid The molar heat capacity is 65.6 J/(Kmol) for the vapor.
