    The balanced chemical reaction is expressed as:

    8SO2 + 16H2S = 3S8 + 16H2O

    We are given the initial amount of the reactants. From there, we determine the limiting reactant. We do as follows:

    87.0 g SO2 (1 mol / 64.07 g) = 1.36 mol SO2 (16 mol H2S / 8 mol SO2) = 2.72 mol H2S

    87.0 g H2S (1 mol / 34.08 g) = 2.55 mol H2S (8 mol SO2 / 16 mol H2S) = 1.28 mol SO2

    Therefore, the limiting reactant would be H2S. We calculate the maximum amount of S8 that can be produced from the amount of H2S.

    2.55 mol H2S (3 mol S8 / 16 mol H2S) (256.48 g / 1 mol) = 122.63 g S8
