46. Solving a chemistry problem

206. Determine the diameter of the aerosol particles using the result of the study by the method of in-line ultramicroscopy: 87 aerosol particles (smoke from open-hearth furnaces) were counted in a volume of 2.2⋅10^-2 mm^3. The aerosol concentration is 1∙10^-4 kg/m^3, the density of the dispersed phase is 2 g/cm^3, the particle shape is spherical.
