   What is the empirical formula of Fe 2 O 3?

   • Given that the molar mass of the oxide is 159.69 g mol –1. ∴ The empirical formula of the oxide is Fe 2 O 3. n Molar Mass Emprical formula mass ∴ n = Molar Mass Emprical formula mass Molecular formula of a compound is obtained by multiplying the empirical formula with n. Thus, the empirical formula of the given oxide is Fe 2 O 3 and n is 1.

   Jul 21, 2022 · Determining Empirical Formulas. An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen.
