Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

Identify the molecular ion and the base peak in this mass spectrum (Circle or label them). The molecular ion indicates the presence of a set of isotopes. What are those isotopes?
