About the Mole Calculator

This calculator helps you convert between mass, moles, and number of particles using the chemical formula of a substance.

Key Concepts:

• 1 mole = 6.022 × 10²³ particles (Avogadro's number)
• Molar mass is the mass of 1 mole of a substance (g/mol)
• The mole is the SI unit for amount of substance

Common Calculations:

1. Mass to Moles: moles = mass (g) / molar mass (g/mol)
2. Moles to Mass: mass (g) = moles × molar mass (g/mol)
3. Particles to Moles: moles = particles / 6.022e23
4. Moles to Particles: particles = moles × 6.022e23
