Question

1. Explain the terms-the number average molar mass and the mass average molar mass of a
polymer giving suitable expressions for them.​

Answer 1

Answer:

my dear friend your answer is

Explanation:

The distribution of molecular weights in a polymer sample is often described by the ratio of the weight average molecular weight to the number average molecular weight. In this case the ratio is 531,600/500,000 = 1.063. This ratio is the Polydispersity Index (or PDI).
