At constant volume the heat of combustion of a particular compound is -3952.0 kJ/mol. When 1.555g of this compound (molar mass=130.13g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 7.429 degrees celsius. What is the heat capacity (calorimeter constant) of the calorimeter?
