The combustion of benzoic acid releases 26.38kJ/g and is often used to calibrate a bomb calorimeter. the combustion of 1.045 g of benzoic acid caused the temperature of the calorimeter to rise by 5.985C. Useing the same calorimeter, a sample of 0.876g of octane (C8H18) was burned. The temperature increased by 8.518C. What is the molar enthalpy of the combustion of octane?
