Nuclear density, $\rho =\frac{\text{mass}}{\text{volume}}=\frac{\mathrm{mA}}{{\displaystyle \frac{4}{3}}\mathrm{\pi }\left({\mathrm{AR}}_0^3\right)}=\frac{3\mathrm{m}}{4{\mathrm{\pi R}}_0^3}$

As nuclear density is not a function of mass number of atom therefore, nuclear density is the same for all nucleus that is $2.97\times {10}^{17} \mathrm{kg} {\mathrm{m}}^{-3}$
