Nuclear Physics-nucleus diameter

[prolong199]

could someone please leed me in the right direction for calculating an atoms atomic mass given the diameter of its nucleus? thanks

If you assume that the density of nuclei are about the same and equal to the density of a proton, then all you have to know is the diameter of a proton $_1^1H$

i found that the diameter of a proton is 1x10^(-15)m with atomic mass 1, but how do i calculate the atomic mass of an atom with diameter 8x10^(-15)m?

What is the ratio of volume of the larger nucleus to that of the proton? If each nucleon (a proton or neutron) has the same volume, what does that tell you about the number of nucleons in the larger nucleus?

Isn't this basically the same as this question ? https://www.physicsforums.com/showthread.php?t=120210
