1.3 Having assumed that each particle in a silver ash is a cube with an edge length l = 4 * 10–8 m, determine how many colloidal particles can be obtained from 1 · 10–4 kg of silver. Calculate
the total surface of the obtained particles and calculate the surface of one silver cube with a mass of 1 · 10-4 kg The density of silver is 10.5 · 103 kg / m3.
