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. the mass spectrum of h_2 is taken under conditions that prevent decomposition into h atoms. the two naturally occurring isotopes of hydrogen are^1h (atomic mass = 1.00783 a mu; abundance 99.9885%) and^2h (atomic mass = 2.01410 a mu; abundance 0.0115%). how many peaks will the mass spectrum have? express your answer as an integer. give the relative atomic masses of each of these peaks. express your answers using six significant figures. enter your answers in ascending order separated by commas.
