Question

Consider given reaction and calculate mass of [E] (in gm) yield of reactions in each step is given in bracket. and also find the molecular weight of [D]. Sum of mass of [E] and molecular weight of [D] is your final answer.

[Given atomic weight of Na = 23, C = 12, N = 14, O = 16, H = 1, Cl = 35.5, Pb = 207.2, S = 32, Ba = 137]

(CH₃)₂S = 15.50/62 = 0.25 mol;

Na₂S = 0.25 × 0.9 = 0.225 mol (90%);

PbS = 0.225 mol (100%);

SO₂ = 0.225 × 0.8 = 0.18 mol (80%);

SO₂Cl₂ [D] = 0.18 mol (100%), M(D) = 135;

BaSO₄ [E] = 0.18 mol × 233 = 41.94 g.

Sum = 41.94 + 135 = 176.94.
