1. Suppose 0.7542 g of magnesium reacts with excess oxygen to form magnesium oxide as the only product, what would be the theoretical yield of the product? 2. If 0.8922 g of magnesium oxide is obtained from the reaction indicated in #1 above, what would be the percent yield of the magnesium oxide? 3. Suppose the percent yield was calculated to be over 100%, what possible reasons could you give to account for it?
