For a linear polymer molecule, the total chain length L depends on the bond length between chain atoms d, the total number of bonds in the molecule N, and the angle between adjacent backbone chain atoms , as follows: L=Ndsin(2) Furthermore, the average end-to-end distance for a series of polymer molecules r in Figure 14.6 is equal to r=dN Calculate the repeat unit molecular weight of polyethylene in g/mol.
