A certain mass spectrum shows three peaks. The first is at m/z = 39.5 Daltons with a relative abundance of 100%, the second is at m/z = 40.0 Daltons with a relative abundance of 5.8%, and the third is at m/z = 40.5 Daltons, with a relative abundance of 0.1%. What is the charge on the ion? If the molecule is of the form CnHxOyNz, propose a plausible formula. Any of n, x, y, or z may be zero.
I am having trouble finding the charge let alone the formula. Please help me!
