Now for this question we need to know what is the exact meaning of mass density over nucleus, right? and mass density or density actually refers to just mass, sorry, mass over volume.
00:19
Now this is the very general definition of density.
00:23
And the mass that we are talking about of an arbitrary nucleus would just be the nucleon number, which is a total number of nucleons in the nucleus multiplied by u, the atomic mass unit.
00:44
And the volume that we are talking about, all right, so this is the mass, the volume that we're talking about will be, we're assuming it to be a sphere, so the volume is faltered by r cube.
00:58
But what is the radius? radius of the atom.
01:03
And usually we approximate it to be about r0 multiplied by the atomic number, total number of nucleons, sorry, nucleon number, to the power of one third.
01:19
This is an approximation based on experiments.
01:23
R0 is just a constant, which you can find...
