Question

For the question(s) that follow, consider the following balanced equation. Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH 3 (g) -When 36.0 g of H₂O react, how many grams of NH₃ are produced?

The molar mass of H₂O is 18.0 g/mol, so 36.0 g of H₂O is 2 moles. According to the balanced equation, 6 moles of H₂O produce 2 moles of NH₃. Therefore, 2 moles of H₂O produce 2/3 moles of NH₃. The molar mass of NH₃ is 17.0 g/mol, so 2/3 moles of NH₃ is 11.3 g.
