Consider a chain-growth polymerization. If the propagation rate constant is 37 L mol^-1 s^-1, the termination rate constant is 26 L mol^-1 s^-1, the initiator dissociation rate constant is 2 x 10^-4 s^-1, the initiator efficiency is 0.4, the monomer concentration is 2.3 mol/L, and the initiator concentration is 1.8 millimoles/L, what is the weight average degree of polymerization of the resulting polymer? Assume termination happens via 50% combination and 50% disproportionation. (Note that useful equations for this situation are provided in the textbook 2nd edition, chapter 3, problem 7).
