Assume you are computing oxygen-16 nucleus, there are 8 protons and 8 neutrons, you use the mass of neutron and proton to compute the mass of oxygen-16 nucleus.

[br]mass of proton = 1.6727 \times 10^{-27} \text{ kg}[br]mass of neutron = 1.6750 \times 10^{-27} \text{ kg}[br]mass of oxygen-16 = 8 \times 1.6727 \times 10^{-27} + 8 \times 1.6750 \times 10^{-27}[br]

I believe you can press the calculator yourself. :smile:
