306. When observing the Brownian motion of gum particles in water with observation time intervals of 60 seconds, the root-mean-square shift of 10.65 microns was established. The particles have a spherical shape with a radius of 0.212 µm, the temperature of the experiment is 17 °C, the viscosity of water is 1.09 10-3 Pa*s. Calculate the Avogadro constant Na from this data, knowing the gas constant R.
