111. Solving a chemistry problem

Using the Smoluchowski equation, calculate and plot the change in the total number of particles during the coagulation of sulfur hydrosol. The dispersity of the initial sol is 0.05 nm-1, the concentration is 6.5 mg/l, the density of sulfur is 0.9 g/cm3. The viscosity of the dispersion medium at 295 K is 0.001 Pa s. Take the time intervals equal: 1; 2; four; 10 and 20 s.
