An English chemistry professor needs a cup of hot tea before grading 50 homeworkassignments but his electric water heater is broken . In his lab, however, he doeshave some ethanol (CH3CH2OH, MW=46.07gmol-1) and 1 gram of benzoic acid(C6H5COOH, MW=122.12 gmol-1). He knows that the benzoic acid has an enthalpyof combustion, H, of -3226.7 kJmol-1. In a constant volume (bomb) calorimeterinitially at 293.15 K, he finds that the combustion of 1.000 g of benzoic acidincreased the temperature to 297.67 K. In the exact same calorimeter, 1.000 g ofethanol raised the temperature from 293.15K to 298.38K.(a) What is the enthalpy of combustion for 1 mole of ethanol? I am confused about this question and I need help.
