The solution for the question is posted, but please show how to get intermediate step for Na=50.461, Nt=49.951, and Nb. =1. Hydrolysis of an aromatic polyamide with a number average molecular weight of 24,116 g/mol gives 39.31% by weight of m-amino aniline, 59.81% by weight terephthalic acid, and 0.88% by weight benzoic acid. a. Draw the repeat unit structure of the polymer. b. Calculate the degree of polymerization and the extent of reaction. c. Calculate what the degree of polymerization would have been it the amount of benzoic acid was doubled.
