Sulfur trioxide,SO₃,is made from the oxidation of SO₂as follows: 2SO₂ + O₂ $\to$ 2SO₃ A 21-g sample of SO₂ gives 18 g of SO₃.The $\underline{\text{ percent yield }}$ of SO₃ is .

Quizplus · Accepted Answer

To find the percent yield of SO₃, we need to use the formula: Percent yield = (actual yield/theoretical yield) x 100 Theoretical yield of SO₃ can be calculated using stoichiometry: 2 mol SO₂ produces 2 mol SO₃ Therefore, 21 g SO₂ produces (2 x 80 g)/2 = 80 g SO₃ Actual yield = 18 g Now, substitute the values in the formula: Percent yield = (18/80) x 100 = 22.5% The answer closest to 22.5% is option B (69%).
