Empirical and Molecular Formulae

The Empirical Formula of a compound is the simplest whole-number ratio of
atoms of each element present in a compound ­ the simplest mole ratio.
Empirical formulae are calculated from the masses of the elements in a
compound. The best way to work it out, I…

Formula
Now, you have to divide the amount of mol of each element by the
smallest number of moles you have ­ in this case, it's 0.125. ...And from this,
you're given a ratio, and therefore the Empirical formula!
