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. WebApr 9, 2024 · Solution: From the given molecular formula it is clear that the given chemical substance has 2 iron atoms and 3 oxygen atoms. Now, the atomic weights of iron and oxygen atoms are 55.847 amu and 15.9994 amu respectively. Thus, the molecular weight of Fe2O3 is = 2* (atomic weight of iron) + 3* (atomic weight of oxygen) = 159.692 amu.
