The number of molecules of gas (reactants plus products) that are present when the reaction is complete is to be calculated. Concept introduction: A limiting reagent is the one that is completely consumed in a chemical reaction . The amount of product formed in any chemical reaction has to be in accordance with the limiting reagent of the reaction. Amount (mol) of excess reactant is reactant left after the formation of the maximum amount(mol) of products. The formula to calculate moles is as follows: Amount ( mol ) = mass molar mass (1)
