What's the way to convert n(r) to [itex] \rho(r) [/itex] in case of a spherical cloud.(adsbygoogle = window.adsbygoogle || []).push({});

n(r) is the column density, [itex] \rho(r) [/itex] is the density.

I tried (but didn't manage) to get it from their relation to the total mass:

[itex] M = 4 \pi \int r^2 \rho(r)dr = 2 \pi \int r n(r)dr [/itex] (is it correct anyway?)

Thank you,
