Explanation:

Hello!

In this case, since the empirical formula of compounds whose by-mass compositions are known, is computed by first computing the moles considering those compositions as actual masses:

Next, we divide each moles by the fewest ones, in this case those of oxygen to obtain the subscript in the empirical formula:

Thus, we obtain:
