These relative weights computed from the chemical equation are sometimes called equation weights. But at the same time, this molar mass (as many now prefer to call it) is also the observable mass of one mole (NA) of the substance, so we frequently emphasize this by stating it explicitly as so many grams (or kilograms) per mole: g mol1. Finding molar mass starts with units of grams per mole (g/mol). Suppose that we have \(N\) carbon atoms, where \(N\) is a number large enough to give us a pile of carbon atoms whose mass is 12.0 grams. Again, use the ratio format.
