The electrical conductivity of copper is 5.96 x 10^7 S/m; its atomic weight is 65.546 AMU; the charge on the electron is 1.06 x 10-19 coulombs; the density of copper is 8.92 g/cm^3. Assume there is one free electron per copper atom. Calculate the mobility in cm^2/volt-sec. This is a question from my electronics lab course and i am not sure how to even start with it. This problem probably isn't that difficult but i have no idea what equations to use since my prof thinks that everyone knows much more than they do and rarely tells us what equations to use. Any help with this would be really appreciated.
