Heat of combustion of benzoic acid $(C_{6} H_{5} C O O H)$ at constant volume at $25^{0}$ is 3233KJ/mole. When 0.5g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by ${0.53}^{0} C$ . Now in the same bomb calorimeter 1g of $C_{2} H_{6}$ burnt then temperature increased by ${2.04}^{0} C$ . $△ H$ for combustion of $C_{2} H_{6}$ is?
