gollark: The equation is 4FeS2 + 11O2 --> 2Fe2O3 + 8SO2. You want to know how many moles O2 are needed per mole FeS2, so that's 11/4 = 2.75. Then, since the question asks for how many moles O2 are needed with *3* moles FeS2, multiply by 3, and you get 8.25.
gollark: The answer is just (3/4)*11 then, which is 8.25.
gollark: Oh, FeS2, not Fe2O3.
gollark: <@288035900980461579> Could you photograph the question or something? It does definitely look like you need 16.5 moles O2 for 3 moles Fe2O3, so the question is probably asking something else?
gollark: 2Fe2O3 is 2 moles Fe2O3, 11O2 is 11 moles O2.
