A sample of benzene, C6H6, weighing 3.51 g was burned in an excess of oxygen in a bomb calorimeter. The temperature of the calorimeter rose from 25.00 C to 37.18 C. If the heat capacity of the calorimeter is 12.05 kJ/K, what is the molar energy of combustion for benzene? Also, what would be the value of q for burning 50.3 g of benzen at constant volume and 25.00 C?
