Homework Statement
I have to use mass spectometry to find out what chemical compound this is based on the positions and relative abundances of the peaks used in identifying it.
mass/charge (amu/e-) (1st column) --->Relative Abundance (2nd column)
14--->0.7
25--->2.5
26--->10
27--->20.3
28--->6.1
32--->1.5
35--->4.6
36--->1.8
37--->1.5
38--->0.6
47--->2.5
48--->3
49--->20.2
50--->1.4
51--->6.6
59--->0.8
60--->4
61--->12.7
62--->100
63--->13.9
64--->33
65--->3.1
98--->8.2
100--->5.2
102--->0.9
Homework Equations
Molar Mass of Cl=35,37; Carbon=12; Oxygen= 16, Hydrogen=1
The Attempt at a Solution
I know that this compound contains carbon, hydrogen, and probably oxygen (not sure though). It also contains chlorine because the molecular ion peak is at 98 and there's another small peak two amy/electric charges ahead at M+2=100. There's also a small peak at 35 and 37 which is the molar mass of chlorine. There isn't any sulfur or nitrogen in the compound. I don't know what the possible formulas would be for a compound that could add up to 98 or 100. Also, I hear that there's a book or reference which gives all the chemical formulas possible at a given mass/charge therefore it would give all the possible formulas for a peak at 50 or 51 or 63 or 65 etc.
