Two samples of polystyrene, samples A and B, were synthesised. A from the addition of n- butyl lithium to styrene in THF under a nitrogen atmosphere, and B from the addition of benzoyl peroxide to styrene under a nitrogen atmosphere respectively. 1. Of the two polymers produced (A and B) one had Ma = 12,000 and a polydispersity of 1.1 and one a Ma=11, 200 and a polydispersity of 1.7. Identify which set of molecular weight parameters corresponds to which polystyrene sample.

22-30. (a) The mean free path is the average distance a molecule travels before colliding with another molecule. The mean free path, A, is given by A = kT/(V20P), where k is Boltzmann’s constant, T is temperature (K), P is pressure (Pa), and o is the collision cross section. For a molecule with a diameter d, the col- lision cross section is nd. The collision cross section is the area swept out by the molecule within which it will strike any other molecule it encounters. The magnetic sector mass spectrometer is maintained at a pressure of ~103 Pa so that ions do not collide with (and deflect) one another as they travel through the mass analyzer. What is the mean free path of a molecule with a diam- eter of 1 nm at 300 K in the mass analyzer?
