• In the real world, amounts of reactants and products are typically measured by mass or by volume.
  • It is first necessary to convert the given quantities of each reactant to moles in order to identify the limiting reactant.
  • Silver metal reacts with sulfur to form silver sulfide according to the following balanced equation.
  • The amount of S required to fully react with all of the Ag is 0.232 moles.
  • Since there is more sulfur present than what is required to react, the sulfur is the excess reactant and silver is the limiting reactsant.
