Molecular and Emperical FormulasMeasuring Elements ProcessesSteps to Stoich- given--> moles --> molar ratio--> solve Percent Yield: Actual/Theoretical x 100= percent yield Theoretical Yield = the value for the Limiting Reactant Percent composition= mass of element / mass of compound Empirical Formula= %mass-->grams-->moles-->molar ratio-->whole number(if needed) Molecular formula = molecular mass / empirical mass x emp. subscripts Finding Excess Reactant- sample of LR-->moles-->mole ratio of excess-->mass or volume of excess used Excess sample - excess used = amount of excess or Product amount of excess minus product amount of LR -->moles-->mole ratio-->mass or volume of excess Solutions StoichiometrySource of Powerpoint:
