The obvious way would be to look for the parent peak (the peak caused by the unfragmented molecular ion) at the end of the spectrum but how can you tell the parent peak from one caused by heavier isotopes? Also how do you know if there's a parent peak at all and that all the peaks aren't fragments? Are there any tricks I should know about for finding the molecular weight from the mass spectrum?
