A mass spectrum of a sample of antimony showed two peaks at m/z= 120 and m/z= 122. The relative atomic mass of this sample of antimony is 121.3. Use these data to calculate the ratio of the relative abundances of the two isotopes.

121 = 50:50 abundance
Therefore, each 0.5 is worth 25% abundance Therefore, each 0.05 is worth 2.5% abundance
