Expert Answer
Density of nucleus = mass / volume
Let A be the mass number of nucleus and m be mass of nucleon ( proton or neutron)
Mass of nucleus = A × m
Radius R of the nucleus is
R = Ro A1/3 .
where Ro is a constant
Volume = (4/3) π R3 = (4/3) π Ro3 A
Hence denisty ρ of nucleus is
From above expression , we see that density of nucleus is constant .
Hence ratio of nuclear density of He+ and Li++ is 1 : 1
