1. Assuming that in a colloidal solution of silver each particle is a cube with an edge length of 4*10-6 cm and a density of 10.5 g/cm3, calculate: a) how many colloidal particles can be obtained from 0.1 g of silver; b) what is the total surface area of all silver particles? Indicate the type of dispersed system under consideration, according to the classification based on the degree of dispersion of dispersed phase particles.
