Description

To determine the value of Avogadro´s number was observed under the microscope distribution of the colloidal particles of gamboge, suspension in water as a function of height. In one series of measurements we obtained the following results (at 15° C): P height, m 5 35 Mean relative number of particles n at height h over a period of time 100 47 The particle density 1,206 g/cm3; the density of water is 0.999 g/cm3. The radius of particles of 0.212 µm. Calculate Avogadro´s number from these data.
