The amount of iron ( II ) chloride that can be obtained by the reaction of 3.17 g of iron with excess of hydrochloric acid is to be calculated. Concept introduction: The stoichiometry of a chemical species involved in a chemical reaction represents the number of chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product. The stoichiometry of a chemical species is also represented by number of moles. The number of moles of a substance is given by the expression shown below. n = m M
