Calculate the amount of heat energy, in units of kilojoules, required to convert 50.0 g of liquid ethanol, ch3ch2oh, at 25.5°c to gaseous ethanol at 92.0°c. (cethanol liquid = 2.44 j/g°c; cethanol gas = 1.42 j/g°c; molar heat of vaporization of liquid ethanol = 3.86 × 104 j/mol. the boiling point of ethanol is 78.4°c.)
