Question

Two nuclei have mass number in the ratio 1:2, what is the ratio of their nuclear densities?

Answer 1

given$,$ the ratio of mass number is $1:2$

Nuclear density is inversely proportional to mass number$.$

Therefore$,$

$\frac{{\rho }_1}{{\rho }_2}=\frac{A_1}{A_2}=\frac{2}{1}=2:1$

We get$,$ $2:1$
