 stoichiometry the study of the measurable relationships that exist in chemical formulas and reactions mole-to-mole problem when you convert moles of one substance to moles of another (law of conservation of matter) (get the moles to grams, so 2 mol X ? g/? mol) (major categories of stoichiometry problems) (mass-mass, mass-volume, volume-volume) mass-mass problem you are given the mass of one substance and are asked to find the mass of another substance in the same reaction mass-volume problem you are given the mass of one substance and asked to find the volume of another volume-volume problem you are given a volume and asked to find a volume (volume-volume problem) (number you have X the ratio of the two) little equation thingy quantity of given - convert to moles - moles of given - use molar ratio - moles of unknown - convert to desired units - quantity of unknown limiting reactant the reactant that limits the amount of product formed in a chemical reaction (the quantities of products formed in a reaction are always determined by the _____ of the limiting reactant) (quantity) expected yield the amount of a product that should be produced based on calculations actual yield the amount of a product that is really obtained from a chemical reaction percent yield what percent of the expected yield was actually obtained (percent yield) (actual yield/expected yield X 100%) (the coefficients in a balanced chemical equation represent the ___________ of _______ of each substance) (relative number, moles) (mole calculations can be used to verify that ___________) (mass is conserved in a chemical reaction)
