What mass of methane must be combusted to produce 1.00 x 10^3 kJ of heat?

Question

could someone write the equation and the answer?

Thank You.

Answer 1

Look in your text or notes (or tables) and find the heat of combustion for CH4. It should be given in kJ/mol.

moles CH4 x kJ/mol = 1.00 x 10^3 kJ. Solve for moles CH4 and convert to grams.
