.
) is scaled up to a mole, since it has the molar mass, and both carbon (
) and oxygen (
) are also scaled up in the same magnitude. The empirical formula is of the form:
, 
are the number of moles of the carbon and oxygen, respectively.
), no unit, is calculated by the following formula:
(1)
- Mass of hydrogen, in grams.
- Molar mass of hydrogen, in grams per mole.
and 
, then the scale factor is:
