Question: In a living anionic polymerization experiment, styrene (9.2 g) was added to 60 mL of tetrahydrofuran (THF) containing 3.3 x 104 mol of sodium naphthalene

In a "living" anionic polymerization experiment, styrene (9.2 g) was added to 60 mL of tetrahydrofuran (THF) containing 3.3 x 104 mol of sodium naphthalene (C10H3Na, electron transfer initiator). Polymerization was carried out at a fixed temperature and after completion an additional 7.7 g of styrene in 50 mL of THF was added. The final yield of polystyrene reached approximately 100% conversion. Calculate the number average molecular weight of the final polymer
