Here's the question. If you know how to do it, it would be very helpful if you could share the answer and the work that you did to get the answer. Thanks

A 1.103 g sample of a gaseous compound that occupies a volume of 582 mL at 765.5 Torr and 25.00 ?C is burned in an excess of O2(g) in a bomb calorimeter. The products of the combustion are 2.108 g CO2(g), 1.294 g H2O(l), and enough heat to raise the temperature of the calorimeter assembly from 25.00 to 31.94 ?C. The heat capacity of the calorimeter is 5.015 kJ/?C. Write an equation for the combustion reaction, and calculate ?H? in kJ/mol for this reaction at 25.00 ?C.
