Take the mass measurement with nitrogen (28 dalton or atomic mass units per molecule) and the mass measurement with helium (4 daltons per atom) and use the difference between the measured masses to find the mass of 1 dalton (one atomic mass unit) in grams. The standard value of the dalton is 1.66053906660×10−27 kg with an uncertainty of ±50 in the last two figures. Can you identify the sources of error in your measurement?
