A bomb calorimeter is calibrated by combusting 1.558 g of benzoic

A bomb calorimeter is calibrated by combusting 1.558 g of benzoic acid (MW = 122.2 g/mol) in the chamber. The temperature of the water is increased by 2.34 K. The enthalpy of combustion of benzoic acid is -3230 kJ/mol. After determining the calorimetric constant the very same bomb calorimeter is used to determine the enthalpy of combustion of liquid benzene(MW = 78.0 g/mol). The combustion of 1.234 g of benzene increased the temperature of the surrounding water by 2.93°C .What is the enthalpy of combustion of benzene?Provide work and equations used
