Follow these steps to estimate the electrical conductivity of silver at temperature T = 300 K. The density of silver is rho = 10.5 g/cm³ and the molar mass is M = 108 g/mol.
(a) Determine the concentration of conduction electrons in silver assuming that each silver atom contributes one electron.
(b) Use the equipartition of energy theorem (see e.g. Chapter 1 if you are unfamiliar with this) to estimate the average speed of conduction electrons.
(c) Estimate the mean free path of conduction electrons by equating it to the nearest-neighbor distance in the lattice. The latter must be estimated based on the numbers provided and the fact that metallic silver forms an fcc lattice.
(d) Combine the results of (a-c) to calculate the electrical conductivity.
