Which is the appropriate atomic mass of an atom with 16 neutrons?

The atomic mass of an atom is the sum of the number of protons and neutrons in its nucleus. Therefore, if an atom has 16 neutrons, its atomic mass would be the total of the protons and neutrons. For example, if the atom has 8 protons, the atomic mass would be 16 (neutrons) + 8 (protons) = 24.
