Chapter 2, Problem 80IAE

The two naturally occurring isotopes of chlorine are ${}^{\text{25}}\text{Cl }\left(\text{34}\text{.9689 u, 75}\text{.77\%}\right)$ and ${}^{\text{27}}\text{Cl }\left(\text{36}\text{.9658 u, 24}\text{.23\%}\right)$ . The two naturally occurring isotopesof bromine are ${}^{\text{72}}\text{Br }\left(\text{78}\text{.9133 u, 50}\text{.69\%}\right)$ and ${}^{\text{81}}\text{Br }\left(\text{80}\text{.9163 u, 49}\text{.31\%}\right)$ . Chlorine and bromine combine to form bromine monochloride, BrCl. Sketch a mass spectrum for BrCl with the relative number of molecules plotted against molecular mass (similar to Figure 2.14).
