I think you will have to give us a bit of context here.


Are you trying to determine the formula of magnesium oxide from first principles? Given that it is a binary compound, we predict a formula of #Mg_(x)O_y#. Of course, we know that magnesium oxide has a formula of #MgO#, (i.e. #x=y=1#), but the experiment that established this formulation would not be straightforward.
