Explanation:

Hello there!

In this case, since these problems about formulas, firstly require the determination of the empirical formula, assuming that the given percentages are masses, we can calculate the moles and mole ratio of oxygen to iron as shown below:

$n_{Fe}=70/55.85=1.25\\\\n_O=30/16=1.875$
