The electrical conductivity and the electron mobility for some
metal at room temperature are 7.6 ×
107 (Ω-m)-1 and 0.0026 m2/V-s,
respectively.
(a) Compute the number of free electrons per cubic meter for this
metal at room temperature.
(b) What is the number of free electrons per metal atom? Assume
a density of 8.9 g/cm3 and an atomic weight of
63.55 g/mol.
