Search: Magnesium reacts with oxygen to form magnesium oxide. If 0.81 grams of magnesium oxide are formed, how many grams of oxygen reacted?

Number of results: 16,130

Chemistry
Thank you very much for your assistance preemptively. My question has to do with law of conservation of mass. A 50g sample of iron reacts with 21g of oxygen to from how many grams of iron oxide? Is the answer maybe 71g or 29g. This is stumping me.
