Answer to Question #106408 in Chemistry for Mari

Question

1.60 g O2 is reacted in excess S , if the percent yield of the reaction is 95.0% what is the yield of SO2

Answer 1

The reaction between O₂ and S can be shown as following:

S + O₂ = SO₂

The theoretical yield of SO₂ produced in the reaction can be calculated using the equation:

m(SO₂) = m(S) × Mr(SO₂) / Mr(S) = 1.60g × 64.066 g/mol / 32.065 g/mol = 3.20 g

If the yield of the reaction is 95.0%, the actual yeald of SO₂ is:

Actual yield = % yield × theoretical yield / 100% = 95.0% × 3.20 g / 100% = 3.04 g

Answer: 3.04 g
