It is common in mass spectrometry to assume that the mass of a cation is the same as that of its parent atom. (a) Using data in Table 2.1, determine the number of significant figures
that must be reported before the difference in masses of \({ }^{1} \mathrm{H}\) and \({ }^{1} \mathrm{H}^{+}\) is significant.
