Why is nuclear density same for all nuclei?

Explanation

Since the density of the nucleus is given as `("mass of nucleus")/("volume of nucleus") = A/(4/3 pi(r_(0)A^(1//3))) = 3/(4pi(r_(0))^(3))`
and the volume of nucleus is dependent on mass of the nucleus, the nuclear density is independent of both mass number and volume and remains same.
