How much energy (in kilojoules) is released when 30.0 gg of ethanol vapor at 91.0 CC is cooled to -19.0 CC? Ethanol has mpmp = -114.5 CC, bpbp = 78.4 CC, HvapHvap = 38.56 kJ/molkJ/moland HfusionHfusion = 4.60 kJ/molkJ/mol. The molar heat capacity is 113 J/(Kmol)J/(Kmol) for the liquid and 65.7 J/(Kmol)J/(Kmol) for the vapor.
