Question 6 (9 points) Polymer has a distribution of molecular weight, which will affect its physical property such as viscosity and osmotic pressure. Molecular weight data for some polymer are tabulated here. Compute (a) (3 points) the number-average molecular weight, (b) (3 points) the weight-average molecular weight. (c) (3 points) If it is known that this material's degree of polymerization is 710, what is the repeat unit molecular weight m?
