How do you determine molecular weight
Webmoles dsDNA = mass of dsDNA (g)/molecular weight of dsDNA (g/mol) molecular weight of dsDNA = (number of base pairs of dsDNA x average molecular weight of a base pair) + 36.04 g/mol average molecular weight of a base pair = 617.96 g/mol, excluding the water molecule removed during polymerization. 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.
