WebApr 28, 2024 · Multiply M gO by 2 to balance the oxygens. M g(s) + O2(g) → 2M gO(s) Multiply M g on the left side by 2 to balance the magnesiums. 2M g(s) +O2(g) → 2M gO(s) Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced. Answer link WebHow many moles of O₂ are required to form 5.00 moles of H₂O? Solution: 5.00 mol H₂O × 1molO₂ 2molH ₂O = 2.50 mol O₂. If the question had been stated in terms of grams, you would have had to convert grams of H₂O to moles of H₂O, then moles of H₂O to moles of O₂ (as above), and finally moles of O₂ to grams of O₂.
