The Mole Vocabulary STEMscopes

Avogardro’s Number

• Expressed as 6.02 x 10^23; the number of representative particles contained in one mole of a substance.

• A notation showing the lowest whole-number ratio of atoms in a compound; does not necessarily show the actual numbers of each type of atom in the compound.

• The sum of atomic weights in an empirical formula.

• A general expression used to refer to the mass (in grams) of a mole of any substance, expressed as grams per mole, or g/mol

Empirical Formula

• A notation showing the lowest whole-number ratio of atoms in a compound; does not necessarily show the actual numbers of each type of atom in the compound.

• The sum of atomic weights in an empirical formula.

• A general expression used to refer to the mass (in grams) of a mole of any substance, expressed as grams per mole, or g/mol

• The SI unit used to describe the number of number of particles (atoms, molecules, ions) of a substance that are present in a sample; 1 mole is equal to 6.02 x 10^23 particles of a substance; 1 mole corresponds to the number of carbon atoms in exactly 12 g of pure carbon.

Formula Mass

• The sum of atomic weights in an empirical formula.

• A general expression used to refer to the mass (in grams) of a mole of any substance, expressed as grams per mole, or g/mol

• A notation that shows the number of each type of atom present in each molecule of a chemical compound.

• The sum of the atomic masses of a molecular compound.
