Dear student
The weight of oxygen in water = 88.89 g The weight of hydrogen in water = 100-88.89 = 11.11 g the weight of sulphur in sulphur dioxide = 50g weight of oxygen sulphur dioxide = 100 -50 = 50g The weight of sulphur that combines with 88.89 g of oxygen = 50/50 x 88.89 = 88.89g The ratio between the weights of sulphur and hydrogen which combine with a fixed weight of oxygen 88.89: 11.1 = 8:1 -----1 The weight of hydrogen = 5.88g The weight of sulphur in hydrogen sulfide = 100 - 5.88 = 94.12g The ratio between weights of sulphur and hydrogen is 94.11: 5.89 =16:1 --------2 from the two equations 1 and 2 we get the ratios 8/1 :16/1 =8:16 = 1:2 From the answer, we are able to know that these are simple multiples of each other. hence here Law of reciprocal proportion is verified.
