A 0.530-g sample of nonanedioic acid (C9H1604) is burned in a bomb calorimeter and the temperature increases from 24.00 °C to 26.73 °C. The calorimeter contains 1000 g of water and the bomb has a heat capacity of 793 J/°C. The heat capacity of water is 4.184 J g-1°C-1. Based on this experiment, calculate AE for the combustion reaction per mole of nonanedioic acid burned. x 10^____ kJ/mol
