Solution

2 g of Oxide gave 0.2517g of H2O
In
And again 2g of another oxide gave 0.4526g H2O
According to the law of multiple proportions:
If two elements can combine to form more than one compound, then
the masses of one element that combine with a fixed mass of the other element are in small whole
number ratios.
Here also
Ratio of mass of water produced in both the reactions = 0.2517g: 0.4526g â‰¡ 1:2
