    You perform mass spectrometry on trypsin-digested peptides of 1g protein.
    a) One of the detected peptide ions has a +1 charge and an m/z ratio of 1267.78. What is the mass of this peptide in daltons?
    b) One of the other peptides ions has a +2 charge and an m/z ratio of 943.62. What is the mass of this peptide in daltons.
