Ethanol, CHsOH, boils at 78.29 C. How much heat energy (in kilojoules) is required to heat 1.40 kg of this liquid from 23.0°C to the boiling point and then change the liquid completely to a vapor at that temperature? (The specific heat of liquid ethanol is 2.44 3/g-K and its enthalpy of vaporization is 38.56 k)/mol.)
