    Well, you have many different reactions with different molar heat...

    If you know the amount of heat given by x moles of substance, then the heat one mole of substance gives off is obtained by simple proportion.

    Or, if that is not what you are asking for, you have Hess's Law saying the total heat involved for a reaction to take place is equal to the total heat involved for another reaction to take place provided the reactants at the start and the products at the end are the same.
