In the following reaction, how many grams of ferrous sulfide (fes) will produce
0.56 grams of iron (iii) oxide (fe2o3)?
4fes + 7o2 → 2fe2o3 + 4so2
the molar mass of ferrous sulfide is 87.92 grams and that of iron (iii) oxide is 159.7 grams.

First find no. of moles of Fe2O3 formed
next find the no. of moles of FeS by mole ratio
next find the mass of FeS
mass of FeS = 0.617g
