A 1.107-g sample of benzoic acid (HC;H;O:) is burned in an excess of O:(g) in a bomb calorimeter, which is immersed in water. The reaction produces heat that causes the temperature of the water and bomb to increase from 24.96 to 29.20°C. (a) If the heat capacity of the calorimeter is 6.90 KJºC, how many kilojoules of heat are produced by the combustion of 1.107 g of benzoic acid? (b) Calculate the heat of combustion per gram of benzoic acid and the molar enthalpy of combustion of benzoic acid.
