How many grams of H₂O will be formed when 39.0 g H₂ is mixed with 49.6 g O₂ and allowed to completely react to form water?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the formation of water is 2H₂ + O₂ → 2H₂O. The molar mass of H₂ is 2 g/mol, and O₂ is 32 g/mol. 39.0 g of H₂ is 19.5 moles, and 49.6 g of O₂ is 1.55 moles. O₂ is the limiting reactant. 1.55 moles of O₂ will produce 3.10 moles of H₂O. The molar mass of H₂O is 18 g/mol, so 3.10 moles of H₂O is 55.8 g.
