What number of moles of ammonia can be produced from 7.46 g of hydrogen gas and excess nitrogen gas?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the production of ammonia is N2 + 3H2 → 2NH3. The molar mass of H2 is 2.02 g/mol. Therefore, 7.46 g of H2 is 7.46 / 2.02 = 3.69 mol H2. According to the stoichiometry of the reaction, 3 mol of H2 produces 2 mol of NH3. Thus, 3.69 mol of H2 will produce (3.69 * 2) / 3 = 2.47 mol of NH3.
