Answer to Question #198164 in Chemistry for Jordan Weissert

Question

How many moles of ammonium sulfate can be made from the reaction of 30.0 moles of ammonia and sulfuric acid? 

NH₃ + H₂SO₄ → (NH₄)₂SO₄

Answer 1

Solution:

Balanced chemical equation:

2NH₃ + H₂SO₄ → (NH₄)₂SO₄

According to the equation above: n[NH₃]/2 = n[(NH₄)₂SO₄]

Therefore,

n[(NH₄)₂SO₄] = n[NH₃] / 2 = 30.0 mol / 2 = 15.0 mol (NH₄)₂SO₄

Answer: 15.0 moles of ammonium sulfate can be made.
