4 FeS(s) + 7 O2(g) ==> 2 Fe2O3(s) + 4 SO2(g)
7.82 moles of FeS are required to produce 3.91 moles of Fe2O3
What is the maximum number of liters of Fe2O3(s) that can be made from 10.95 L of O2(g) and 18.64 L of FeS(s) at STP?
The problem here is "liters" of Fe2O3? and Liters of FeS? These are not gases, and something is wrong....
