At constant volume, the heat of combustion of a particular compound is -3698.0 KJ/mol. When 1.895 g of this compound (molar mass=181.06 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 8.009C. What is the heat capacity (calorimeter constant) of the calorimeter?
