    Answer:-

    156.88 gram

    Explanation:-

    The balanced equation for the reaction is

    4NH3 + 5O2 = 4NO + 6H2O

    Molecular mass of NH3 = 14 x 1 + 3 x 1 = 17 gram

    Molecular mass of NO = 14 x 1 + 16 x 1 = 30 gram

    From the balanced equation for the reaction,

    4 NH3 will give 4 NO.

    ∴ 4 x 17 grams of NH3 will give 4 x 30 gram of NO

    88.9 grams of NH3 will give (4 x 30) x (88.9) / (4 x 17)

    = 156.88 gram
