13. Using the Debye equation, calculate the molecular weight of polystyrene and the second virial coefficient, using the following data on measuring the light scattering of solutions of polystyrene in toluene:
Solution concentration c, g/l 1.11 1.45 1.88 2.43 2.87
Turbidity of solution t*108, m-1 3.68 4.47 5.55 6.50 7.13
take the constant H equal to 1.17 * 10-13.
