Determine the mass defect $($in u$)$ for $($a$)$ helium$-3(2$He$3),$ which has an atomic mass of $3\mathrm{.}016030$ u$,$ and $($b$)$ the isotope of hydrogen known as tritium $(13),$ which has an atomic mass of $3\mathrm{.}016050$ u$.($c$)$

On the basis of your answers to parts $($a$)$ and $($b$),$ state which nucleus requires more energy to disassemble it into its separate and stationary constituent nucleons.
