Question
how many grams SO2 are produced when 20(g) FeS2 reacts with 16(g) O2?
4FeS2(g)+15O2(g)=2Fe2O2(s)+8SO2(g)
4FeS2(g)+15O2(g)=2Fe2O2(s)+8SO2(g)

I doubt the Fe2O2. More likely to be Fe2O3 or FeO. I would go with Fe2O3.
4FeS2 + 11O2 ==> 2Fe2O3 + 8SO2
Convert 20 g FeS2 to moles. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles FeS2 to moles SO2.
Convert moles SO2 to grams. g = moles x molar mass.
