Expert Answer:

According to law of definite proportions, every chemical compound contains fixed and constant proportions(by mass) of its constituent elements. A sample of pure water will always contain 88.8% by mass of oxygen and 11.1% by mass of hydrogen. H2O contains H and O in a fixed ratio by mass. It explains athe law of constant proportions, thus they are divided in ration of 1:8. So, Mass of oxygen is 88.8%.
