Your equation doesn't make sense to me. I assume you mean something like this.
4FeS2 + 11 O2 ==> 2Fe2O3 + 8SO2
Convert 64 g SO2 to moles. moles = grams/molar mass.
Using the coefficients in the balanced equation, convert moles SO2 to moles FeS2.
Convert moles FeS2 to grams. grams = moles x molar mass.
Post your work if you get stuck.
What amount (in moles) of FeS2(s) are required to produced 64g of SO2(g) according to the following equation?
4FeS2(s) + 110(g)_________2FeO3(s)__8SO2(g)...remember the first long bar is an arrow.
