In the following reaction, how many grams of ferrous sulfide (FeS) will produce 0.56 grams of iron (III) oxide (Fe2O3)?

Question

In the following reaction, how many grams of ferrous sulfide (FeS) will produce 0.56 grams of iron (III) oxide (Fe2O3)?
4FeS + 7O2 d 2Fe2O3 + 4SO2

The molar mass of ferrous sulfide is 87.92 grams and that of iron (III) oxide is 159.7 grams.

mols Fe2O3 desired = grams/molar mass Convert mols Fe2O3 to mols FeS using the coefficients in the balanced equation. g FeS = mols FeS x molar mass FeS
