Equal volumes of gases at the same temperature and presure contain equal numbers of partucules

The number of representative particules conained in one mole of a substance; equal to 6.02 x 10^23 particules

A dormula with the lowest whole number ratio of elements in a compound: tge empirical formula of hydrogen peroxide (H2O2) is HO

A term used to refer to the mass of a mole of any substance

The volume occupied by 1 mole of a gas at standerd temperature and presure (STP) 22.4 L

The amount of a substance that contains 6.02 x 10^23 representives particules of that substance

The percent by mass of each element in a compound

The smallest unit into which a substance can be broken down without a change in compostion, usually atoms, molecules or ions

the conditions under which the volume of a gas is usually measured: standerd tempurature is 0*C and standers preaure = 101.3 kPa
