The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to product. Consider the reaction: 2 Fe(s) + 3 Cl₂(g) → 2 FeCl3(s) If 9.920 g Fe is mixed with 16.62 g Cl₂, calculate the theoretical yield (g) of FeCl3 produced by the reaction.

Step 2
Compare the ratio of amounts of reactants present to the ratio of the stoichiometric coefficients of the reactants to determine which is the limiting reactant.
Step 3
Calculate the amount (mol) of product formed by complete consumption of the limiting reactant.
