    2. S. No.

      		 Compounds Chemical formula Ratio by mass of the combining elements
      (a) Ammonia NH3

      N:H = 14:3

      (b)

      		 Carbon monoxide CO

      C:O = 12:16

      C:O = 3:4
      (c) Aluminium fluoride HCl

      H:Cl = 1:35.5

      (d)

      		 Aluminium fluoride AlF3

      Al:F = 27: (19 × 3)

      Al:F = 27: 57

      Al:F = 9:19
      (e) Magnesium sulphide MgS

      Mg:S = 24:32

      Mg:S = 3:4
