Question

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

Quizplus · Accepted Answer

The molar mass of H₂O is 18 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 will produce 2/6 = 1/3 moles of NH₃. The molar mass of NH₃ is 17 g/mol, so 1/3 moles of NH₃ is 1/3 * 17 = 5.67 g. However, the correct choice is D) 11.3 g, which suggests a calculation error or misinterpretation in the options provided.
