. 66g of ammounium sulphate is produced by the action of ammonia on sulphuric acid

66g of ammounium sulphate is produced by the action of ammonia on sulphuric acid.

Write a balanced equation and calculate:

(a) Mass of ammonia required.

(b) The volume of the gas used at the S.T.P.

(c) The mass of acid required.

2NH₃ + H₂SO₄ → (NH₄)₂SO₄

66 g

(a) 2NH₃ + H₂SO₄ → (NH₄)₂SO₄

34 g98 g132 g

For 132 g (NH₄)₂SO₄ = 34 g of NH₃ is required

So, for 66 g (NH₄)₂SO₄ = 66 ×32/132 = 17 g of NH₃ is required

(b) 17g of NH₃ requires volume = 22.4 litres

So, Mass of acid required, for 66g (NH₄)₂SO₄= 66×98/132 = 49g
