I really wanted to understand the finding of the degree of polymerization of the polymers, as well as in determining the monomer unit of the polymer to be able to determine its molecular weight, thank you for the help:)

2. What is the degree of polymerization of the following polymers; CH,OH +CH,- +N-CH2)-C+ +OCH,CH,00 OH a HO (1) (2) (3) (4) a) With molecular weight of 120,000. b) With molecular weight of 100,000 c) With molecular weight of 80,000. d) With molecular weight of 150,000
