Question

Volume $\left(V\right)$ of the nucleus is related to mass number $\left(A\right)$ as

• A. $V\propto A^2$
• B. $V\propto A^{1/3}$
• C. $V\propto A^{2/3}$
• D. $V\propto A$

Answer 1

Answer: (D)

Radius (R) of nucleus is related with mass number $(A)$ as $R\propto A^{1/3}$
Now, Volume $\propto R^3\propto A$
