ESI-TOF MS of a protein from a low pH solution generates a series of m/z peaks. The two most dominant successive peaks have m/z values of 510.0 and 502.9.
a. Calculate the molecular weight of the protein and the charges carried by the protein in these peaks (i.e., z values).
b. How do these charges compare to the average number of charges a protein of this size would be expected to have at low pH. Explain.
