Heating an ore of antimony (Sb2S3) in the presence of iron gives the element antimony and iron(II) sulfide.

Sb2S3(s) + 3 Fe(s) 2 Sb(s) + 3 FeS(s)

When 10.9 g Sb2S3 reacts with an excess of Fe, 9.84 g Sb is produced. What is the percent yield of this reaction?

could you please give me the answer to this problem, im struggling with it. THANKS!!
