To begin the experiment, a bomb calorimeter is filled with 1.11 g ch4 and an excess of oxygen. the heat capacity of the calorimeter, including the bomb and the water, is 4.319 kj g c⋅°. the initial temperature of the system was 24.85°c, and the final temperature was 35.65°c.

using the formula ∆h =−m ⋅ c ⋅∆t , solve for the heat of combustion of. 1.11 g ch4.
