We are asked which is responsible for the peak at a mass of 30.0106
Calculate the mass of each given:
A) Mass of 12C21H6 = 2 x mass of 12C + 6 x mass of 1H
= 2 x 12.0000 + 6 x 1.007825 = 30.04695
In using a mass spectrometer, a chemist sees a peak at a mass of 30.0106. Of the choices 12C21H6, 12C1H216O, and 14N16O, which is responsible for this peak? Pertinent masses are 1H, 1.007825; 16O, 15.994915; and 14N, 14.003074.
