case 1: Iron (3) sulphide contains 46.3% by mass of sulphur, and 53.7% by mass of Fe.
case 2: Also Iron (2) sulphide contain 36.50% by mass of S and 63.50% by mass of Fe.a) Calculate the mass of sulphur which combine with 1gm of Iron in case 1 and in case 2 above

b) what is the ratio of mass of sulphur which combined with 1 gm of Fe from Iron (3) sulphide (case 1) to the ratio of Sulphur which combined with 1gm of Fe from Iron (2) Sulphur, in (Case 2 ).
