Question

1. The fertilizer ammonium sulfate is prepared by the reaction between ammonia and sullfuric acid:

2NH₃(g) + H₂SO₄(aq) -> (NH₄)₂SO₄

a. What is the molar mass of NH₃?

b. What is the molar mass of (NH₄)₂SO₄?

c. What is the mole-mole ratio of NH₃ to (NH₄)₂SO₄?

d. How many moles of ammonium sulfate is produced when 638.4 g of NH₃ reacts completely with H₂SO₄?

e. How many grams of NH₃ is needed to produce 50.0 g of (NH₄)₂SO₄?

Answer 1
