    I have question on my revision work. Hope someone around here is able to help

    Why is it a good approximation to assume that the relative mass of the G+, cations, calculated from the mass spectrometry, is the same as the relative atomic mass of Ga?

    Thanks in advance!

    Assuming you mean Ga+
    Because electrons have a tiny mass, even compared to protons and neutrons, around 1/1838. So the mass spec, and the Ar are very similar.

    As above, the mass of the electron lost during the ionisation is essentially not observable to us. If you consider the fact that an electron weighs 9.11x10-31 kg then it's obviously impossible to measure this with weighing scales.

    Oops! yes, assuming it's Ga+
