1 Stoichiometry Vocab Theoretical Yield: the calculated amount of product yielded by a reaction (found through stoichiometry) Actual Yield: the actual amount of product yielded by physically performing the reaction Percent Yield: __actual yield__ x = % yield theoretical yield

2 Stoichiometry Vocab Molar Mass: the mass obtained by adding up the weights of all the atoms in a compound Given: the value (a number) that is given in a stoichiometry problem; look for a number and then moles or grams ex: 3.0 moles of CH4 or 23.0 g of NaCl Wanted: the quantity that the problem is asking you to find; look for “How many…” or “Calculate…” ex: How many grams of CH4 are produced… Calculate the moles of NaCl required…

3 Stoichiometry Vocab Limiting Reactant (Limiting Reagent): the reactant that limits how much product you can make; can change depending on how much of each reactant you have Excess/Sufficient: usually refers to reactants; not a factor in stoichiometry since it means you have more than enough and it will not be a limiting reactant Mole Ratio (Molar Ratio): ratio of any substances in a balanced equation; used to convert one quantity in a reaction to another
