Chapter 8: Problem 17
An element, \(\mathrm{X}\), have three isotopes \(\mathrm{X}^{20}\) \(\mathrm{X}^{21}\) and \(\mathrm{X}^{22}\). The percentage abundance of \(\mathrm{X}^{20}\) is \(90 \%\) and its average atomic mass of the element is \(20.18\). The percentage abundance of \(\mathrm{X}^{21}\) should be (a) \(2 \%\) (b) \(8 \%\) (c) \(10 \%\) (d) \(0 \%\)
