Statement-1: Number average and mass average polymeric mass is nearly same in most of natural polymers.

Statement-2: Number of monomeric units are nearly same in most of the natural polymers.

The number of molecules in a unit mass of polymer must be counted in order to use the average molecular weight (Mn) measuring technique. In the majority of natural polymers, the mass average is the same. because the majority of natural polymers have a very uniform number of monomeric units.
