146. Solving a chemistry problem
10. Using the ultramicroscopy method in the air flow in the volume W = 2 × 10 -11 m 3, 80 cubic aerosol particles - the smoke of open-hearth furnaces - were calculated. Determine the average length of the edge of the particle if the weight concentration of the aerosol is C = 10.6 × 10 -5 kg / m 3; density ρ = 2⋅10 3 kg / m 3.
