How much energy in J is needed to convert 48 g of liquid ethanol at 67 oC to vapor at 97oC. You might need to know that: mp = -114 oC and bp = 78oC The heat of fusion is 4.6 kJ/mol and the heat of vaporization is 46.0 kJ/mol. Finally, the specific heats of the solid, liquid and gas are, respectively 2.1, 3.2 and 1.8 J/g oC.
