According to chemist John Dalton, if one mole of nitrogen is combined with three moles of hydrogen to form one mole of ammonia (knowing that nitrogen, with an atomic number of 7, has an atomic mass of 14, and hydrogen, with an atomic number of 1, has an atomic mass of 1), then this compound will have an atomic weight (or molecular mass) of:
14 grams per mole (14 daltons)
17 grams per mole (17 daltons)
20 grams per mole (20 daltons)
22 grams per mole (22 daltons)
43 grams per mole (43 daltons)
