How much energy (in kilojoules) is released when 33.0 {rm g} of ethanol vapor at 95.0^circ {rm C} is cooled to -19.5^circ {rm C}? Ethanol has {rm mp} = -114.5 ^circ {rm C}, {rm bp} = 78.4 ^circ {rm C} , Delta H_{rm vap} = 38.56 {rm kJ/mol} and Delta H_{rm fusion} = 4.60 {rm kJ/mol}. The molar heat capacity is 113 {rm J / left( K cdot mol right)} for the liquid and 65.7 {rm J / left( K cdot mol right)} for the vapor.
