Solving a problem in physics section 32 paragraph 8 el

8. Iron conductor (ρ = 7,87 g / cm 3, M = 56 · 10-3 kg / mol) of section S = 0,5 mm2 current flows I = 0,1 A. Determine the average velocity of ordered (directed) motion electrons, assuming that the number of free electrons n per unit volume of the conductor is equal to the number of atoms n ´in the unit volume of the conductor.
