I have previously posted this question, but now I am lost

question:
A calorimeter is filled with 10.0 millimole (mmole) of methane gas and an excess of oxygen. When burned, the ignition wire releases 107.2 J of heat. The heat capacity of the calorimeter (including the bomb and water) is 4.319 kJ oC-1.
The initial temperature is 24.75 degrees celsius and the final temperature is 26.85 degrees celsius

Calculate ΔHcomb for methane and determine the thermochemical reaction for the combustion of methane
