A polystyrene sample is prepared in tetrahydrofuran at a concentration (Cm) of 0.02 g/L and it is characterized by osmotic pressure and light scattering. The second virial coefficient (A2) equals 3.5x10-4 mol.L.g?. You will use R = 8.3145 J.K1.mol1 and T = 298 K. Question 1: The osmotic pressure experiment yields the following result: II¡Cm = 0.42 m.s-2 Calculate the molecular weight in g/mol of this sample. This molecular weight is a number average molecular weight. True False
