60. Solving a chemistry problem
50. The osmotic pressure of gold hydrosol (spherical particle shape) with a concentration of 2 g / l at 293 K is 3.74 Pa. Calculate the diffusion coefficient of hydrosol particles under the same conditions, if the density of gold is 19.3 g/cm3, and the viscosity of the dispersion medium is 1*10-3 Pa*s.
