1. You have two bags of polymer. Bag A has 10 kgs of polymer with weight average molecular weight of 336.6 kg and Bag B has 20kg of polymer with weight average molecular weight 392.7kg. Bag A has a polydispersity of 1.2 and Bag B has a polydispersity of 1.4.
a. What is the number average molecular weight of each bag?
b. If the polymer is polyethylene (mer = C2H4) what average polymerization (chain length) by weight for each bag?
c. If you combine the two bags what is the weight average and numerical average molecular weight of the mixture?
