Term | Definition |
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. |
