Conversion Factor

A factor used to convert between units, represented as a ratio.

Molar Mass

The mass of one mole of an element, expressed in grams, equivalent to the atomic mass.

Chemical Formula

A representation of a substance using symbols for its constituent elements and numerical subscripts.

Subscripts

Numbers in a chemical formula that indicate the number of atoms of each element in a molecule.

Mole of Atoms

1 mole of an element contains 6.02 × 10^23 atoms of that element.

Mole of a Compound
