If M(A; Z), M_p and M_n denote the masses of the nucleus $${}_Z^AX,$$ proton and neutron respectively in units of u (1 u = 931.5 MeV/c²) and BE represents its bonding energy in MeV, then

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE
