Bromine has two naturally occuring isotopes, Br-79 and Br-81, approximately 50% of each.  Bromomethane will contain approximately 50% Br-79 and 50% Br-81.   The mass spectrum peak for methane containing Br-79 will be referred to as the M+ (molecular ion) peak, and the peak for Br-81 will be called the M+2 peak, as Br-81 weighs two more amu than Br-79. What will be the locations of the two bromomethane peaks on the mass spectrum and what will be the approximate ratio of their heights?
