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).
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.
