Examine the chemical reaction and lab scenario.

2Fe2S3+9O2→2Fe2O3+6SO2

3.17 g of iron(III) sulfide (Fe2S3) reacts with an excess amount of oxygen at standard temperature and pressure. The theoretical yield of sulfur dioxide (SO2) is 3.81 g. However, during a lab, only 3.37 g are produced.

What is the percent yield of sulfur dioxide?

94.41% SO2

81.36% SO2

44.00% SO2

88.45% SO2
