Empirical formulas can determined for a variety of compounds. Besides oxygen-containing oxide compounds, sulfur-containing sulfide compounds can be formed by covering the metal sample with yellow sulfur powder. Upon heating, the sulfur is incorporated into the compound, & the excess sulfur powder becomes sulfur dioxide gas. The calculations follow a similar sequence. A 3.500g sample of iron (a transition metal) was covered with sulfur powder & heated to combine the sulfur. 5.509g of iron sulfide product was formed. What is the empirical formula of the iron sulfide product? Type calculations for partial credit. Format your answer as “The empirical formula is ____

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
