Imagine trying to count every grain of sand on a Caribbean beach, impossible, right? Chemists face a similar challenge when counting atoms! That’s why we use a special unit called the mole. One mole of any substance contains 6.02 × 10²³ particles, this is called the Avogadro constant. Think of it as a 'chemist’s dozen', just like a dozen means 12, a mole means 6.02 × 10²³ particles.
