A mole ratio<span> is a conversion factor that relates the amounts in </span>moles<span> of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation. The following six </span>mole ratios<span> can be </span>written<span> for the ammonia forming reaction above.</span>
