Heat of Combustion Calculator

Find energy released per mole of fuel.

Calculated Output

Heat of combustion (kJ/mol) 890

Formula: heat of combustion = energy ÷ moles

Step-by-Step Breakdown

1. Values used:

2. Energy released = 890 kJ

3. Amount burned = 1 mol

5. Heat of combustion = Energy released x Amount burned = 890 x 1 = 890kJ/mol

Did this calculator solve your problem today?

The math behind it

heat of combustion = total energy released ÷ moles burned.

890 kJ from 1 mol methane → 890 kJ/mol.

Per gram?

Divide the per-mole value by the molar mass.
