Considerable variation in polymer chains results during polymerization. The chain lengths play an important role in processing polymers and in their final properties. Although we cannot see the chain lengths of the polymers, their molecular weight provides a good indication of length. Molecular weight is the weight of a single unit or molecule in a compound. To determine the molecular weight of the compound, it is necessary to multiply the weight of a molecule by the number of molecule or monomers. We said polyethylene typically has about 2,000 monomers, so we multiply 2,000 times the molecular weight of one monomer to obtain 56,000.
