Question

In the following reaction: 2 NH₃ + SO₃ + H₂O→(NH₄)₂SO₄ what mass of NH₃ is consumed when 3.3 g of ammonium sulfate is formed?

Quizplus · Accepted Answer

The molar mass of (NH₄)₂SO₄ is 132.14 g/mol. 3.3 g corresponds to 0.025 mol. The reaction shows 2 mol NH₃ per 1 mol (NH₄)₂SO₄, so 0.05 mol NH₃ is needed. The molar mass of NH₃ is 17.03 g/mol, so 0.05 mol corresponds to 0.85 g.
