Key Information

  • Avogadro's Number: 6.022 × 10²³ particles/mol
  • One Mole: contains 6.022 × 10²³ particles (atoms, molecules, or formula units)

Convert Between Mass, Moles, and Particles

The mole is chemistry's counting unit - connecting the mass we can measure to the particles we can't see. This calculator helps you convert between grams, moles, and number of particles using Avogadro's number (6.022 × 10²³).

Understanding Mole Conversions

A mole is 6.022 × 10²³ particles of any substance. The molar mass (g/mol) tells you how many grams equal one mole. From these relationships, you can convert between mass, moles, and particle count.

Key Formulas

n = m/M (moles from mass), N = n × Nₐ (particles from moles)
