What is the mole unit of measurement in stoichiometry?

In stoichiometry, the mole is the unit of measurement that is used to quantify the amount of a substance. One mole of a substance is equal to Avogadro's number of particles (6.022 x 10^23) of that substance. Mole-to-mole ratiOS derived from balanced chemical equations are used to perform calculations in stoichiometry.
