In Mass Spectrometry (MS) the molar mass of compounds can be determined. The so-called "molecular ion" corresponds to the molecular mass when Electron Impact Mass Spectrometry (EIMS, one of several common MS techniques) is used. It is important to realize, though, that the mass detected by MS depends on the isotopes present in the molecule. The questions below try illustrate the impact of isotope distribution in a molecule. What is the molar mass of the compound shown below? What is...
