While experimentally evaluating the empirical formula of magnesium oxide, a scientist determines that the magnesium oxide product contains 0.013 mol of magnesium and 0.0091 mol of oxygen. Thus, the experimentally determined empirical formula of magnesium oxide is: OMg1.430 OMgO0.70 OMg1.40 OMg0.01300.0091
