Question

law definite proportion and eg also?

Answer 1

Law of definite proportion.... 

The amount of each ingredient will double, but the proportions should stay the same. We can think about this principle when defining The Law of Definite Proportions, which states that any chemical compound will always contain a fixed ratio of elements by mass.A French scientist named Joseph Proust conducted experiments that demonstrated this law, from the late 1700's to the early 1800's. The Law of Definite Proportions is also sometimes called Proust's Law.

 For example, the compound water. Whatever the source of water, its composition is that of two atoms of hydrogen and one atom of oxygen.
