Problem

A spherical nucleus has a mass of

3.32\times10^{-25}\,\text{kg}

. Treat the nucleus as uniform matter of density

2.3\times10^{17}\,\text{kg\,m}^{-3}

. a. (i) Determine the volume of the nucleus in

\text{m}^3

. b. (ii) Hence calculate its radius in femtometres. c. (iii) Using

R_0=1.2\times10^{-15}\,\text{m}

, estimate the mass number

A

of this nuclide. Round your answer to the nearest whole number.
