In an experiment, a 0.7455 g sample of 1,2-benzenediol (C6H6O₂) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.363 x 10³ g of water. During the combustion the temperature increases from 25.61 to 28.41 °C. The heat capacity of water is 4.184 J.g¹. C-¹. The heat capacity of the calorimeter was determined in a previous experiment to be 989.7 J. C-¹. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 1,2-benzenediol based on these data. C6H6O2 (s) + (13/2)0₂ (9)→ 3H₂O(l) + 6CO2 (g) + Energy kJ/mol Molar Heat of Combustion =
