What Is a Mole in Chemistry?

A mole is a standard unit used in chemistry to measure the amount of a substance. One mole contains approximately:

6.022 × 10²³ particles

These particles can be atoms, molecules, ions, or other chemical entities.

Because atoms and molecules are incredibly small, chemists use moles to work with manageable quantities of substances. The relationship between grams and moles is determined by the substance's molar mass, which is expressed in grams per mole (g/mol).

Basic Formulas

Moles = Grams ÷ Molar Mass

Grams = Moles × Molar Mass

The calculator automatically performs these calculations and also calculates the number of molecules present.
