010. Solving a chemistry problem
7. In a study using flow ultramicroscopy in a volume V=1.5*10-11 m3, 53 particles of oil mist aerosol were counted. Assuming the shape of the particles to be spherical, determine their average radius. Sol concentration c = 21 * 10-6 kg/m3, density p = 0.92 * 103 kg/m3.
