Sulfur and oxygen react in a combination reaction to produce sulfur trioxide,an environmental pollutant: 2S (s) + 3O₂ (g) → 2SO₃ (g)
In a particular experiment,the reaction of 1.0 g S with 1.0 g O₂ produced 0.80 g of SO₃.The % yield in this experiment is ________.

Question

Theoretical yield of SO₃ is calculated based on the limiting reactant. Sulfur (S) is the limiting reactant. Theoretical yield of SO₃ is 2.5 g. The actual yield is 0.80 g. % yield = (actual yield/theoretical yield) * 100 = (0.80/2.5) * 100 = 32%.
