10. Ferrocene, synthesized in 1951, was the first organic iron compound with Fe-C bonds. An understanding of the structure of ferrocene gave rise to new ideas about chemical bonding and led to the preparation of many useful compounds. In the combustion analysis of ferrocene, which contains only Fe, C, and H, a 0.9437 g sample produced 2.233 g of CO2 and 0.457 g of H₂O. What is the empirical formula of ferrocene.
