44. When studying the scattering of light by solutions of polystyrene in toluene, the following data were obtained:
Solution concentration s, kg/m3 1.0 1.5 2.0 2.5 3.0 4.0
Solution turbidity τ *108, m-1 0.87 1.27 1.66 2.03 2.38 3.05
Using the Debye equation, determine the molar mass M of the polymer and the value of the second virial coefficient A2, if the constant H = 1.17*10-11 m2 *mol/kg2.
