Mole Ratios
A balanced chemical equation is very helpful when the analyst wishes to know how many moles of each reagent participate in the reaction. The coefficients of the individual species indicate the number of moles of that species required for, or produced by, the complete reaction. The ratios between these coefficients are called 'mole ratios' and are instrumental in stoichiometric analyses.
