here I am only considering the charge density of the nucleus, i.e the density of protons.(adsbygoogle = window.adsbygoogle || []).push({});

I know that from mass density i have rho = m/v -> v = m / rho

I'm not sure what mass to use here. Molecular weight? molar mass? where does avagadros number come into it?

then is it simply charge density = q/v

Will the volume calculated from v = m / rho differ from using 4/3 pi r^3 the volume of a sphere?

A little confused on which approach to use.
