The image below is a positive ionization mode Electrospray ionization-mass spectrum (ESI-MS) spectrum for a peptide, obtained using high resolution mass spectrometry. If ionization occurs through de-protonation (assuming that the mass of a proton is 1.0 Da), what is the neutral mass of the peptide, in Da? 627.271 627.604 100 627.938 | 628.271 628.604 628.938 627.0 628.0 629.0 mass/charge (m/z) 628.271 O 626.271 1878.813 1884.813 % Abundance
