Example 9.3: Calculate X_nfor Monomers with Different End Groups

10 molecules of ARB initially

MW_R = 100 , M_eg ~ 18, we neglect MW_eg wrt MW_R.

At time t we have 5 polymer molecules with the following distribution

*Neglecting M_eg

p = fraction of functional groups of A that have reacted.

There are 5 molecules of polymer that remain: 2 of ARB, 1 of AR₂B, and 2 of AR₃B.

We are giving to calculate by three different methods, all of which yield the same result.
