Molar Conversions (Dimensional Analysis)

What is a mole?

The mole (mol) is the SI measure of quantity of a chemical entity, equivalent to the amount of substance containing as many particles as there are atoms in 12 grams of carbon-12.

Avogadro's Number

Avogadro's Number is 6.02 x 10²³, representing the number of particles in one mole of a substance.

Who is Avogadro?

Amedeo Avogadro was an Italian chemist who hypothesized that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

Molar Mass

The mass in grams of one mole of a substance, measured in g/mol, calculated using the atomic masses of its constituent atoms.

How to calculate Molar Mass?

1. Find the atomic mass of each atom in the compound. 2. Multiply by the number of atoms present. 3. Sum the results; the unit is g/mol.

Moles to Grams Conversion

To convert moles to grams, multiply the number of moles by the molar mass of the substance.

Grams to Moles Conversion

To convert grams to moles, divide the mass in grams by the molar mass.

Moles to Particles Conversion

To convert moles to particles, multiply the number of moles by Avogadro’s number.

Particles to Moles Conversion

To convert particles to moles, divide the number of particles by Avogadro’s Number.
