What is the heat of combustion of methane?

Question

A 9.92 g sample of methane, CH4, is burned in excess oxygen producing carbon dioxide gas and liquid water. The reaction occurs in a calorimeter surrounded by 2.50 kg of Include the sign in your answer. Assume the heat released by the reaction is completely asborbed by the water. Use a molar mass of 16.04 g/mol for methane.

Answer 1

2.5 x 4.18 x (temperature rise) x 16.04/9.92

Note that you have forgotten to include the temperature values.

Make sure that you make the final answer negative. It will be in kJ/mol.
