Also provides the atomic number, element name, base atomic weight and formula weight for the calcutated molecular formula. M is the molecular weight of the polymer, dp is the degree of polymerization and the m 0 is the formula weight of the repeating unit. We can find the value of this parameter using the following equation:

Average Molecular Mass = N 1 M 1 + N 2.
