60 grams of FeS2, is burnt in air, how much sulfur dioxide will produce?(a) 16 grams(b) 32 grams(c) 64 grams(d) 128 gramsI got this question in class test.My doubt is from Stoichiometry in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer»

The CORRECT ANSWER is (c) 64 grams

To elaborate: The BALANCED chemical reaction is 4FeS2 + 11O2 -> 2FE2O3 + 8SO2, => amount of SO2 produced = (60/120)*(8/4)*64 = 64 grams.
