# Problem: Mass spectrometry is more often applied to molecules than to atoms. We will see in Chapter 3 in the textbook that the  molecular weight  of a molecule is the sum of the atomic weights of the atoms in the molecule. In mass spectrometry, these molecular weights are measured relative to 1/12 the mass of one atom of 12C and therefore are commonly referred to as relative masses. The mass spectrum of H2 is taken under conditions that prevent decomposition into H atoms.The two naturally occurring isotopes of hydrogen are 1H (atomic mass = 1.00783 amu; abundance 99.9885%) and 2H (atomic mass = 2.01410 amu; abundance 0.0115%).How many peaks will the mass spectrum have?
