Ratio of mass of sulphur per gram palladium in the compound A to compound B = $\frac{0.603}{0.301} = 2$ Ratio of mass of sulphur per gram palladium in the compound B to compound C = $\frac{0.301}{0.151} = 2$ Ratio of mass of sulphur per gram palladium in the compound A to compound C = $\frac{0.603}{0.151} = 4$ The ratio of these masses are small whole numbers. Hence, these masses are consistent with the law of multiple proportions.
