2.71 g sample of sucrose, C6H12O6, (180.2 g/mol) was burned in a bomb calorimeter to form CO2 and H2O. The heat capacity of the calorimeter itself was 883 J/K and it contained 830.1 g of water (c = 4.184 J/g.K). If the temperature increased by 13.2°C, what is ?E (in kJ) for the combustion of 1 mole of sucrose? Enter your answer in exponential form, 1.23x104 = 1.23E4.
