And what we find is we get approximately 55 amu. Now that we know the empirical formula mass, we can simply see what the factor is between the actual molecular mass and the empirical formula mass. So I can take 110 divided by 55 and get a factor of 2. What that tells me is that my actual chemical formula will be C6H6O2.
