For a condensation polymerization between a dibasic acid and a glycol, a material enginee uses 25 moles from each monomer to form polyester and finds that the conversion of reactant is 80%. nHOOC — СH, — СООН + nHО — СН, — НО - CH, - C-0-CH,-0- + 2n H,O C- Use the given information to answer the following: A) What is the polymer molecular weight? B) What is the quantity (moles) of the formed polymer ? C) Prove that M. (repeating unit molecular weight) is the average molecular weight of the structural units where the structural unit is the residue from each monomer.
