Answer:
A sample of pure water,whatever the source always contains 88.8% by mass of oxygen & 11.1%by mass of hydrogen.
The total amount of percentage is 100, therefore they are divided in a constant ratio.
H2O contains H and O in a fixed ratio by mass. It illustrates the law of constant composition or in other words law of conservation of energy. So, they are divided in a ratio of 1:8 therefore mass of Oxygen is 88.8%.
