38. Solving a chemistry problem

18(3). The value of the diffusion coefficient D of surfactant micelles in an aqueous solution at 25 C was experimentally determined. Find the diameter of the micelles, the association number m, and the micellar mass Mmic surfactant if the viscosity of the dispersion medium is n=0.89 mPa*s.
