    Answer: 18 moles of H_2O will be produced.

    Explanation:

    We are given:

    Moles of ammonia = 12 moles

    The given chemical equation follows:

    4NH_3+5O_2\rightarrow 4NO+6H_2O

    By the stoichiometry of the reaction:

    4 moles of ammonia produces 6 moles of water

    So, 12 moles of ammonia will produce = \frac{6}{4}\times 12=18mol of water

    Hence, 18 moles of H_2O will be produced.
