The electrical conductivity and the electron mobility for some metal at room temperature are 7.2 × 107 (Ω·m)-1 and 0.0027 m2/V·s, respectively.
(a) Compute the number of free electrons per cubic meter for this metal at room temperature. Use scientific notation (x.xE+xx).
(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.
