The following information is given for water, H20, at latm: boiling point = 100 C AHvap(100 C)= 40.7 kJ/mol specific heat liquid = 4.18 J/gC At a pressure of 1 atm, kJ of heat are needed to vaporize a 41.0 g sample of liquid water at its normal boiling point of 100 C. The following information is given for ethanol, C2H5OH, at latm: AHvap (78.4 C) = 38.6 kJ/mol boiling point = 78.4 C specific heat liquid = 2.46 J/gC At a pressure of 1 atm, kJ of heat are needed to vaporize a 45.3 g sample of liquid ethanol at its normal boiling point of 78.4 C
