62. Using the idea of installing Perrin to determination Avogadro constant and applying paint particles suspended in water, the Boltzmann distribution, get the volume of the particles, if the distance between the two layers 80 microns number of particulate material in one layer is twice that in the other. The density of the dissolved dye 1700 kg / m3, and the ambient temperature of 300 K.
