Question #103837

4FeS2 + 11O2 > 2Fe2O3 + 8SO2

Given 75.0 grams of iron (IV) sulfide, how many grams of sulfur dioxide are produced?

Expert's answer

"\\nu=m\/M;"

"\\nu(FeS2) =75\/120=0.625 mol."

0.625 : 4="\\nu(SO2)" : 8

"\\nu(SO2) =0.625*8\/4=1.25 mol."

"m=\\nu*M=1.25*64=80 g."

Answer: 80 g.
