The heat capacity of bomb calorimeters are determined by running a known, standard reaction. The combustion of 1.700 mmol of X caused the temperature of a bomb calorimter to rise from 23.650 oC to 26.350 oC. For the case where T = 25.000 oC, Ho = -3436 kJ/mol, and ng = -4 mol gas/mol X for the combustion reaction, determine the heat capacity of the calorimeter.
