Chapter 9, Problem 28(choose chapter or problem)
Aluminum has a density of 2.70 103 kg/m3 at atemperature of 293 K, and its molar mass is 26.98 g.(a) Compute the number of aluminum atoms perunit volume at that temperature. (b) Use the fact thatEF 11.63 eV for aluminum at 293 K to fi nd the numberdensity of free electrons. (c) Combine your resultsfrom (a) and (b) to estimate the number of conductionelectrons per atomthe valence number foraluminum.
