### Mole Ratios & Stoichiometric Relations

Do stoichiometric relations and mole ratios describe the same relationship between substances? What are stoichiometric relations used for? Is it just another way to express a mole ratio?

I believe that molar ratios and stoichiometric ratios are synonymous. They describe the ratio between the number of moles of compounds in a chemical equation.

Stoichiometric coefficients are the numbers written before each compound in a balanced chemical equation that represent the moles of each reactant and product. For example, 2Na(s) + 2H20(l) -> 2NaOH(aq) + [1]H2(g) is the same thing as saying 2 moles Na(s) + 2 moles H20(l) -> 2 moles NaOH(aq) + 1 mole H2(g). Therefore, stoichiometric relations and molar ratios should be the same thing.
