Phosphatidylcholines with a low molecular weight (found, for example, in egg yolk) form spherical micelles in water with an average molar mass of 97.0 kg/mol. The density of dry matter is 1.018 g/cm3. Assuming this density applies to micelles in solution, calculate the radius and diffusion coefficient of micelles at 20°C in water (viscosity 1.00 mPa*s)
