`R = R_0A^(1//3)` (`R_0` = constant, A = Mass Number), R = radius of nucleus. Taking the relation show that of nuclear density does not depend on mass number `A`.

Explanation

The volume of a nucleus =`4/3piR^3 =4/3piR_0^3A`, Mass =Au
`therefore` Density =`A/(4/3piR_0^3A) =3/(4piR_0^3)` , it does not depend on A.
