Answer: Weight average molecular mass:- Weight average molecular weight (Mw) measuring system includes the mass of individual chains, which contributes to the overall molecular weight of the polymer. It is based on the fact that bigger molecules contain more mass than smaller molecules.
Number average molecular mass:-The number average molecular weight (Mn) measuring system requires counting the total number of molecules in a unit mass of polymer irrespective of their shape or size. This means all molecules are treated equally.
