In every way!

Explanation:

Before I start, you categorized this question as NMR, but you are referring to Mass spectrometry.

In Mass spec. the molecular ion has the same mass as the molecule itself. Take for instance water #H_2O#. The molecule weighs 18 mass units. Its molecular ion is #H_2O^+# and weighs the same.
