A chemist wanted to make 100 grams of SO2. She had only 12 grams if sulfur and 4 grams of oxygen. Unfortunately, the amounts of reactants were not enough to make the desired product. How much S and 02 would she need in order to obtain the deisred grams of product with no leftovers?
S + O2 = SO2 + NO LEFTOVER
