A 0.375-g sample of 2-naphthylacetic acid (C12H1002) is burned in a bomb calorimeter and the temperature increases from 25.80 °C to 28.00 °C. The calorimeter contains 1.06x103 g of water and the bomb has a heat capacity of 903 J/°C. Based on this experiment, calculate AE for the combustion reaction per mole of 2-naphthylacetic acid burned (kJ/mol). C12H1002()+27/2 O2(g) —>12 CO2(g) +5 H2O(1) AE = kJ/mol
