They do not, however, have the same m ass/charge ratio (m/z) . Although most of the ions formed are +1 ions, their masses are different. Therefore, the amount of deflection they experience by the electromagnet is different.N2(g) + 3H2(g) → 2NH3 (g) N 2 ( g) + 3 H 2 ( g) → 2 NH 3 ( g) The balanced equation can be analyzed in several ways, as shown in the figure below.

The 13 C isotope is, of course, heavier than 12 C by 1 mass unit. In addition, about 0.015% of all hydrogen atoms are actually deuterium, the 2 H isotope. So the M+1 peak represents those few acetone molecules in the sample which contained either a 13 C or 2 H. Molecules with lots of oxygen atoms sometimes show a small M+2 peak (2 m/z units ...
