If $\displaystyle \mathrm{M}(\mathrm{A} ; \mathrm{Z}), \mathrm{M}_{\mathrm{p}}$ and $\displaystyle \mathrm{M}_{\mathrm{n}}$ denote the masses of the nucleus $\displaystyle { }_{\mathrm{Z}}^{\mathrm{A}} \mathrm{X}$, proton and neutron respectively in units of $\displaystyle \mathrm{u}\left(1 \mathrm{u}=931.5 \mathrm{MeV} / \mathrm{C}^2\right)$ and BE represents its bonding energy in MeV, then :
Official answer
(2)
$\displaystyle M(A, Z)=Z M_p+(A-Z) M_n-B E / C^2$
