1.	Take the example of water and explain the law of constant proportion (At.mass of O is 16u).
Answer» This LAW states that "in a chemical SUBSTANCE, the ELEMENTS are ALWAYS present in definite proportions by mass".For example: In water H2O, hydrogen and oxygen are always present in the ratio of 1:8 by mass, whatever the method or source from which water is obtained.Massof 2 hydrogen atom=2Mass of ONE oxygen atom=16Hence, ratio of hydrogen and oxygen by mass=2:16=1:8
