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)

- Another fossil-fuel gas used in cooking appliances is "propane", used commonly in backyard grills and RV/camping stoves. Propane is a bigger hydrocarbon: 3 carbons single-bonded in a chain, and the remaining bonds are taken by hydrogen. Its formula is C3H8 and its structure is shown below. KEY POINT: the products are the same as the combustion of methane, but more is produced. The graphic below shows that one propane molecule reacts with 5 oxygen molecules to form molecules of carbon dioxide.
