3.28 g of toluene (C7H8) is burned in a bomb calorimeter. The following reaction occurs.
C7H8(l) + 9 O2(g) → 7 CO2(g) + 4 H2O(l)
The temperature of the calorimeter changes from 21.3°C to 37.8°C. Given that the heat capacity of the calorimeter is 8.42 kJ/°C, find the amount of heat generated per mole of toluene.
