Explanation:
Compound A:
Mass of sulphur = 0.603g
Mass of Palladium = 0.397g
0.603g of sulphur combine with 0.397g of Palladium.
Therefore, 1g of sulphur will combine with = 0.397 / 0.603 = 0.658g of Palladium
Compound B:
Mass of sulphur = 0.301g
Mass of Palladium = 0.699
0.301g of sulphur combine with 0.699g of Palladium. Therefore, 1g of sulphur will combine with
= 0.699 / 0.301 = 2.322g of Palladium
Compound C:
Mass of sulphur = 0.151g
Mass of Palladium = 0.849g
0. 151g of sulphur combine with 0.849g of Palladium,
Therefore 1g of sulphur will combine with = 0.849/ 0.151 = 5.623g of Palladium
Therefore, the masses of Palladium which combine with a mixed mass (1g) of sulphur are in ratio
0.658 : 2.322 : 5.623 i.e 1: 4 : 9 which is a simple ratio
