What mass of NH₃ is prepared from the reaction of 10 g of N₂ with excess H₂?

Question

Quizplus · Accepted Answer

The balanced equation for the reaction is N2 + 3H2 → 2NH3. The molar mass of N2 is 28 g/mol, so 10 g of N2 is 10/28 = 0.357 mol. From the stoichiometry of the reaction, 1 mol of N2 produces 2 mol of NH3, so 0.357 mol of N2 produces 0.714 mol of NH3. The molar mass of NH3 is 17 g/mol, so the mass of NH3 produced is 0.714 mol × 17 g/mol = 12.138 g, which rounds to 12 g.
