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
