| mole | The SI unit used to describe an amount of matter. It is equal to 6.02 x 1023 particles, 22.4L for a gas under standard conditions and a substances atomic mass in grams for mass. |
| % Composition | The % of an element in a compound by mass. |
| empirical formula | The lowest whole number ratio of elements in a compound. |
| molecular formula | The actual formula, usually representative of a covalent compound. |
| stoichiometry | The study of mass relationships in a chemical reaction. |
| molar volume | The volume of mole of any gas at STP, 22.4 L. |
| molar mass | The sum of the atomic masses for a compound, the mass of one mole of that substance in grams. |
| Avogadro | The cool guy that developed the concept of the mole by studying gasses. |
| limiting reactant | The reactant that is depleted first in a chmical reaction. |
| excess reagent | A reactant that does not react completely in a chemical reaction. |
| theoretical yield | The reasult of a stoichiometric calculation. The maximum amount of product that can be formed in a reaction. |
| actual yield | The amound of a product that is actually produced by experiment. |
| percent yield | The percent of the theoretical yield that actually formed. |
