3. Observing the diffusion-sedimentation equilibrium of selenium hydrosol particles at 293 K, it was discovered that with a density difference of 50 µm, one of them had 839 particles, and the other 580. The density of selenium is 4.7 g/cm3, the diameter of the particles is 120. Find what value of Avogadro's number was obtained in this experiment.
