. 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.

 

Best Answer

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

(c) Mass of acid required, for producing 132g (NH4)2SO4 = 98g

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