Mass spectrometry can reveal the presence of isotopes of an element in a compound being analyzed. Isotopes, as separate peaks, can most easily be seen next to the molecular ion peak. Chlorine has two isotopes: Chlorine-35 (abundance 76 %) and chlorine-37 (abundance 24 %). If chloromethane (CH₃Cl) is subjected to mass spectrometry, how many molecular ion peaks will the mass spectrum have?
