To determine the MW of a purified protein you subject it to ESI mass spectrometry. The spectrum shows a series of peaks with two of the most prominent neighboring peaks having m/z ratios of 1885.6 and 1996.4.
What is the MW of the protein? Please show steps.
1996.4 = (M+z)/z 1885.6 = (M+z+1)/(z+1)
Solve for z=17
a. 20000
b. 33922
c. 42420
d. 110355
e. Not enough information
