Question:medium

If the ratio of the nuclear radii of two atoms is $2:3$, then the ratio of their mass numbers is:

Show Hint

Radius goes with the cube root ($\sqrt[3]{A}$), so mass numbers will always go with the cube ($R^3$). Cubing the given terms right away ($2^3 = 8$ and $3^3 = 27$) yields the solution in under two seconds.
