What is not true about mass spectrometry?   Question 13 options:   Only the molecular ion and cationic fragments are deflected, and they are then separated by their mass-to-charge ratio (m/z)   It is used to determine the molecular weight and molecular formula of a compound.   In a mass spectrometer, a compound is converted into ions, which are then separated by a magnetic field.   In a mass spectrometer, a compound is first vaporized and then bombarded with electromagnetic radiation which generates a radical cation that is symbolized by (M)+•   A molecular ion is often very unstable and susceptible to fragmentation

You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C₃₄H₃₂FeN₄O₄, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 34.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?   -don't prematureley round
