a.) The vapor pressure of ethanol is 1.00 × 102 mmHg at 34.90°C. What is its vapor pressure at 55.7°C? (ΔHvap for ethanol is 39.3 kJ/mol.) answer in mmHg

b.) Calculate the amount of energy (in kJ) necessary to convert 357 g of liquid water from 0°C to water vapor at 182°C. The molar heat of vaporization (Hvap) of water is 40.79 kJ/mol. The specific heat for water is 4.184 J/g · °C, and for steam is 1.99 J/g ·°C. (Assume that the specific heat values do not change over the range of temperatures in the problem.)
