Molecules of nitrogen trichloride(NCl) were abalyzed using the mass spectrometer. The following table gives the naturally occuring isotopes of the two elements
Isotopes relative abundance
14N 99.6%
15N 0.4%
35 Cl 75.8%
37Cl 24.2%
Assume that there was no dissociation in the molecules and only singly charged ions were detected in the experiment.
(a) For the three highest peaks in the spectrum, state the identity and their m/c ratio for each of these peaks
(b) cakculate the relative heights of the three peaks in (a) scaling the most abundant peak to 100
