Stoichiometry
Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because

The strong base and strong acid reacts in aqueous solution
Only OH⁻ and H⁺ ions react in every case
The salt formed does not hydrolyse
The strong base and strong acid reacts completely
