4.184g of benzoic acid was burnt in bomb calorimeter. The rise in the temperature is 10^@ . The heat capacity of calorimeter and its contents is 2.644 kcal K^(-1) . Calculate the heat of combustion of benzoic acid.

Heat of combustion of benzoic acid (C_(6)H_(5)COOH) at constant volume at 25^(@)C is -3233 kJ/mole. When 0.5 g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by 0.53^(@)C . Now in the same bomb calorimeter 1g of C_(2)H_(6) burnt then temperature increased by 2.04 C . DeltaH for combustion of C_(2)H_(6) is
