Learning Goal:To understand how to use stoichiometry to convert between quantities of reactants andproducts in chemical equations.Stoichiometry describes the quantitative relationships among the reactants andproducts of a balanced reaction by directly comparing mole ratios. Stoichiometry canbe used to convert mass, number of moles, or number of particles between productsand reactants, as shown in the flowchart displayed in the figure.Substance ASubstance Bnumber ofparticlesAvogadro'snumberAvogadro'snumbernumber ofparticlesIImassmolescoefficients from balancedchemical equationmolesmassmolarmassmolarmassReview | Constants I Periodic TableConverting between quantitiesTo convert from a given quantity of one reactant or product to the quantity of anotherreactant or product:. First, convert the given quantity to moles. Use molar masses to convertmasses to moles, and use Avogadro's number (6.02 x 1023 particles permole) to convert number of particles to moles.• Next, convert moles of the given reactant or product to moles of the desiredreactant or product using the coefficients of the balanced chemical equation.For example, in the chemical equation2H2 + O22H₂Othe coefficients tell us that 2 mol of H₂ reacts with 1 mol of O₂ to produce2 mol of H₂O..Finally, convert moles of the desired reactant or product back to the desiredunits. Again, use molar masses to convert from moles to masses, and useAvogadro's number to convert from moles to number of particles.Reaction of hydrogen and nitrogen to form ammoniaHydrogen gas, H2, reacts with nitrogen gas, N₂, to form ammonia gas, NH3, accordingto the equation3H2(g) + N2(g)→2NH3(g)NOTE: Throughout this tutorial use molar masses expressed to five significant figures.
