Moles Calculator

The Moles Calculator is a powerful chemistry tool used to calculate the number of moles from mass or number of particles. It is essential for students, chemists, and laboratory work.

This calculator simplifies stoichiometry calculations and helps you quickly convert between mass, moles, and particles.

What is a Mole?

A mole is a unit in chemistry that represents a specific number of particles, such as atoms or molecules.

One mole contains:

6.022 × 10²³ particles (Avogadro’s number)

Mole Formulas

There are two main formulas:

Moles = Mass / Molar Mass
Moles = Particles / Avogadro’s Number

How to Use the Moles Calculator
