At constant volume, the heat of combustion of a particular compound is –3334.0 kJ/mol. When 1.569 g of this compound (molar mass = 125.76 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 5.173 °C. What is the heat capacity (calorimeter constant) of the calorimeter?

How many mols did you start with? That's 1.569g x (1 mol/125.76 g) = ? mol.
How much heat was generated. That's
3334.0 kJ/mol x ? mol = ? joules.
?joules = Ccal x delta T.
Solve for Ccal
