Ferrocene, synthesized in 1951, was the first organic iron compound with FeC bonds. An understanding of the structure of ferrocene gave rise to new ideas about chemical bonding andled to the preparation of many useful compounds. In the com-bustion 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?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
