have ten moles of iron atoms in the reactant side of a reaction. Do I have enough information to determine how many moles of iron atoms I will have following the reaction? If so, how many moles of iron atoms will I have at the end of a reaction? If not, what else do I need to know?
To determine the number of moles of iron atoms you will have following the reaction, you need to know the stoichiometry of the reaction. The stoichiometry tells you the balanced ratio of reactants and products involved in the reaction. With this information, you can determine the number of moles of iron atoms produced or consumed in the reaction.
Without knowing the specific reaction or the substances involved, it is not possible to determine the number of moles of iron atoms at the end of the reaction.
