Problem- At constant volume, the heat of combustion of a particular compound is 3184.0 kJ/mol. When 1.661 g of this compound (molar mass = 155.32 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 4.193°C. What is the heat capacity (calorimeter constant) of the calorimeter?
