85.0 grams of H₂S were reacted with 115.0 g of O₂ to produce SO₂ and H₂O. The theoretical yield of SO₂, in grams, is ,Hint: Don't forget to include the coefficients from the balanced reaction in your consideration.

Question

Quizplus · Accepted Answer

The balanced reaction is 2H₂S + 3O₂ → 2SO₂ + 2H₂O. Calculate moles of H₂S (85.0 g / 34.08 g/mol) and O₂ (115.0 g / 32.00 g/mol). H₂S is the limiting reactant. Use stoichiometry to find moles of SO₂ produced, then convert to grams (moles × 64.07 g/mol). The theoretical yield is 153.5 grams.
