How do you determine molecular weight
WebHow do you calculate weight average molecular weight from degree of polymerization? Calculate the molecular weight of the monomer unit by multiplying the atomic mass of each element by the number of atoms in the monomer of each, then add the products. For tetrafluoroethylene, the molecular weight of the monomer unit is 12 x 2 + 19 x 4 = 100. WebThe degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule.. For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by =, where M n is the number-average molecular weight and M 0 is the molecular weight of the monomer unit. …
