4. A colloidal solution of 2.8 kg of mercury dispersed in 1 m3 at 18 C shows an osmotic pressure of 3.45 N/m2. Determine the particle size of the mercury sol: a) the shape of the particles is spherical - the radius of the particles; b) particle shape – cubic – particle edge length. The density of mercury is 13.55•103 kg/m3.
