Explain the law of definite composition in DETAILS and give me examples to support your answer?

Answer 1

Sol :-

From the question definition and example of law of definite composition is given as follows :-

The law of definite proportion, also called Proust's law, or law of constant composition states that a given chemical compound always contain its component elements in fixed ratio or fixed composition (by mass) and it doesn't depend on its source and method of preparation OR we can also states that compounds always contains the same element in same proportion by mass.

For example, oxygen makes up about ⁸/₉ of the mass of any sample of pure water, while hydrogen makes up the remaining ¹/₉ of the mass OR we can say that H2O always contains 11.2% H and 88.8% O by mass whether you have a glass full of water or you are in a swimming pool.
