Solution

The correct option is B

2.85 g


  • In the formation of FeS, the mass ratio of iron to sulphur is 1:1; which means 56 g of iron combines with 32 g of sulphur to form ferrous sulphide.
(Gram atomic mass of iron = 56 g, Gram atomic mass of sulphur = 32 g)
  • Accordingly, 5 grams of iron will combine with 5×3256 g = 2.85 g of sulphur.
  • So, 2.85 g of sulphur would react with 5 g of iron to form FeS.
