Interpretation:Empirical formulafor ferrocene should be written.
Concept introduction:An empirical formula describes the ratio of simplied whole-number of atoms contained in a molecule. The molecular formula tells exact number of each atoms foumd in a molecule.
The steps to determine empirical formula are as follows:
Divide mass of element by its molar mass to convert mass to moles as follows:
Number of moles thus calculated is written as subscript of element’s symbol and this results in a preliminary empirical formula.
In order to convert the moles to the whole number subscripts, each subscript is divided by the smallest subscript.
Sum of the product of molar masses times number of corresponding atoms results in empirical formula mass.

Principles of General Chemistry
- You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.arrow_forward4.84 Aluminum chloride (AlCl3) is used as a catalyst in the production of polyisobutylene, which is used in automobile tires. Scrap aluminum metal reacts with chlorine gas (Cl2) to produce AlCl3. Suppose that 2.70 g of Al and 7.10 g of Cl2 are mixed. What is the maximum mass of AlCl3 that could be formed?arrow_forward4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.arrow_forward
- When heated, potassium chlorate, KClO3, melts and decomposes to potassium chloride and diatomic oxygen. (a) What is the theoretical yield of O2 from 3.75 g KClO3? (b) If 1.05 g of O2 is obtained, what is the percent yield?arrow_forwardSilicon is produced for the chemical and electronics industries by the following reactions.
