Expert Answer:

Atomic Weight: It is also known as atomic mass. Its average mass of atoms of an element which can be calculated by relative abudance of isotopes of an element. It is the weighted average of the masses of natural isotopes.
 
Molecular Weight: It is some of weight of atoms present in one unit of that element.
 
Equivalent Weight:  It is the weight of the substance which can either replace or combine with one mole of Hydrogen or with 1/2 mole of oxygen. The equvalent weight is equal to the atomic weight divided by the valence
