Chemistry - Chemical Kinetics Question with Solution | TestHub

The nucleus of an atom is spherical. The relation between radius of the nucleus and mass number$\mathrm{A}$is given by$\text{1.25}\times \text{1}{\text{0}}^{-\text{13}}\times {\mathrm{A}}^{\frac{1}{3}}\mathrm{ }\mathrm{c}\mathrm{m}$. If radius of atom is one$\mathrm{\AA }$and the mass number is 64, then the fraction of the atomic volume that is occupied by the nucleus is$\left(\mathrm{x}\right)\times 10^{-13}$. Calculate$\mathrm{x}$
