23. Assuming that in the silver sol each particle is a cube whose edge is 0,04⋅10-6 m, determine how many colloidal particles can be obtained from 0.1 g of silver, and compare the total surface of the resulting particles with the surface of a silver cube weight 0.1 g. The density of silver is ρ = 10.5 g / cm3.
