2) A0.500 g sample of Trinitrotoluene (C7H$N2O6) is burned in a bomb calorimeter containing 610 grams of water at an initial temperature of 20°C. The heat capacity of the calorimeter is 420 J°C and the heat of combustion of Trinitrotoluene is 3374 kJ/mol. Using these data, calculate the final temperature of the water and calorimeter once the reaction is complete.
