vocabulary for unit 8 chemistry

TermDefinition
actual yield amount of product produced when a chemical reaction is carried out
Avogadro's number 6.0221367 X 10^23 which is number of representative particles in a mole can be rounded to 6.02 x 10 ^23
empirical formula formula that shows the smallest whole number mole ratio of elements in a compound. it may or may not be the same as the actual molecular formula
excess reactant reactant that remains after a chemical reaction stops
hydrate a compound that has a specific number of water molecules bound to its atoms
limiting reactant reactant that is totally consumed during a chemical reaction, limits the extent of the reaction and determines the amount of product
molar mass mass in grams of 1 mole of any pure substance
mole SI base unit used to measure the amount of a substance. Abbreviated mol the number of carbon atoms in exactly 12 g of pure carbon. also has 6.02 x 10^23 representative particles
mole ratio in a balanced equation ratio between the number of moles of any 2 substances
molecular formula formula that specifies the actual number of atoms of each element in 1 molecule of a substance
percent composition percent by mass of each element in a compound
percent yield ratio of actual yield (from experiment) to theoretical yield (from stoichiometric calculations) expressed as a percent.
stoichiometry study of quantitative relationships between amount of reactants used and products formed by a chemical reaction, is based on law of conservation of mass.
theoretical yield in a chemical reaction the maximum amount of product that can be formed from a given amount of reactant.
