A 5.000 g sample of a hydrocarbon (100.0 g/mol) is completely

A 5.000 g sample of a hydrocarbon (100.0 g/mol) is completely combusted in a bomb calorimeter with a heat capacity (excluding water) of 1500. J/°C. The calorimeter contains 2.500 kg of water (s = 4.184 J/°C•g). The combustion causes a temperature increase of 7.550°C. Calculate the enthalpy of combustion in kJ per mole of the hydrocarbon combusted.
