Question

3 FeS2   +  11 O2   →  Fe3O4   +  6 SO3

100 g of iron sulfide was reacted with excess oxygen, resulting in the production of 100 g of sulfur trioxide. Calculate the percent yield in this reaction.If you need to prepare 800 g of iron oxide, what mass of iron sulfide would you need in your reaction (assuming sufficient oxygen is present) taking into account the percent yield you calculated in c)?
