    14 J of heat

    Explanation:

    Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;

    If 6 moles of the compound produces 84J of heat

    1 mole of the substance will produce 1*84/6 = 14 J of heat
