Express this value as a ratio to the magnetic field found in part a.6. Mass spectrometry uses magnetic field to separate isotopes (same element, but different atomic masses), so we can get the relative abundance of the different isotopes of a given element. For example, Chlorine has two naturally occurring isotopes: Cl-35 has a mass of 5.812 x 10-26 kg and Cl-37 has a mass of 6.144 x 10-6 kg.
