    thank you
    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.


mass of proton = 1.6727 \times 10^{-27} \text{ kg}

mass of neutron = 1.6750 \times 10^{-27} \text{ kg}

mass of oxygen-16 = 8 \times 1.6727 \times 10^{-27} + 8 \times 1.6750 \times 10^{-27}

    I believe you can press the calculator yourself.
