Ethanol, C2H5OH, melts at -114 Celcius and boils at 78 Celcius. The enthalpy of fusion is 5.02 kJ/mol and its enthalpy of vaporization is 38.56 kJ/mol. The specific heat of solid, liquid, and gas is 0.97 J/g-Celcius, and 1.88 J/g-Celcius, respectively. How muh heat to convert 150.0 g of ethanol at /170 Celcius to vapor phase at 78 Celcius?
