Answer to Question #121672 in General Chemistry for mark

Question

If you completed a reaction and found that you produced 650. grams of sulfur dioxide, SO2, how many moles of iron(IV) sulfide, FeS2, reacted?

Answer 1

4FeS₂+11O₂=2Fe₂O₃+8SO₂

It can be seen from the above reaction that 2 mol of SO₂ is formed from 1 mol of FeS₂

Calculate how many FeS₂ are needed to produce 650gr (10.15625mol) of SO₂ given in the task: 10.15625/2= 5.078125mol

Answer: 5.078125mol ≈5 mol FeS₂
