Sulfuric Acid may be produced by the following process:
4FeS2 + 11O2 --> 2Fe2O3 + 8SO2
2SO2 + O2 --> 2SO3
SO3 + H2O --> H2SO4
the right answer is 20.00
please explain why this is, and please also list the steps that you took in order to get the answer

5.00molFeS2 x 2molH2SO4/1molFeS2 = 10 moles H2SO4
A mole of FeS2 has only two moles S in it, regardless of all the coefficients in three lines of equations. Two moles of S can produce a maximum of two moles of H2SO4.

FeS2 contains 2 sulphor atoms
so 5 moles of FeS2 contains 5*2 = 10 moles of sulphor
H2SO4 contains 1 sulphor atom
so the 10 moles of sulphor can form 10 moles of H2SO4
Hence 5 moles of FeS2 can form 10 moles of H2SO4
20 moles is not possible unless there is extra sulphor from somewhere else.
