(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm just trying to understand what the variables in this equation represent. This is part of a study of electrical resistivity lab that I am doing. I don't have my Kittel book with me, and the lab manual for some reason doesn't define these variables.

2. Relevant equations

[tex] \rho = \frac{m}{ne^2} \frac{1}{\tau} [/tex]

3. The attempt at a solution

I could kind of guess at some of them - m = atomic mass, e = elementary charge, [tex]\tau[/tex] = relaxation time...but what about n? And I'm not sure about m, either.

Thanks.
