Extracted text: 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 3.5x104 mol.L.g2. You will use R = 8.3145 J.K-1.mol-1 and T = 298 K. Question 1: The osmotic pressure experiment yields the following result: II/Cm = 0.42 m.s2 Calculate the molecular weight in g/mol of this sample.T This molecular weight is a number average molecular weight.
