All three compounds are similar, but not are the same. To solve it, we multiply each atom's subscript by the n-value: It might seem strange that the n-value is specified.
So this becomes automatically incorrect. It would look exactly like a molecular formula! I could not exactly understand the difference between the molecular formula and empirical formula?
