Calculate which of the following calcium nitrate or ammonium sulphate has a higher % of nitrogen. [Ca = 40, , O = 16, S = 32, N = 14]

Molecular weight of calcium nitrate Ca[NO 3 ] 2 = 40 + 2[(14 + 3(16))] = 40 + 2[14 + 48] = 164 g 164 g of calcium nitrate contains 28 g of nitrogen 100 g of calcium nitrate contains x 100 = 17.07% of nitrogen Percentage by weight of nitrogen in calcium nitrate is 17.07% Molecular weight of ammonium sulphate [NH 4 ] 2 SO 4 = 2[14 + 4(1)] + 32 + 4(16) = 36 + 32 + 64 = 132 132 g of ammonium sulphate contains 28 g of nitrogen 100 g of ammonium sulphate contains x 100 = 21.21% of nitrogen Percentage by weight of nitrogen in ammonium sulphate is 21.21 % Hence, ammonium sulphate has higher concentration of nitrogen than calcium nitrate.

Calculate the percentage by weight of :
(a) C in carbon dioxide
(b) Na in sodium carbonate
(c) Al in aluminium nitride.
[C = 12, O = 16, H = 1, Na = 23, Al = 27, N = 14]
