The Mole & Avogadro's Constant Part 1 — Cambridge IGCSE Chemistry 0620 (3.3) Explained Simply

A dozen means 12. A mole means 6.02 × 10²³. That's it. In this video I explain the mole and the Avogadro constant for Cambridge IGCSE Chemistry (0620), topic 3.3: why chemists need such a huge number, what it counts, and how it lets you count atoms by weighing them. We cover what a mole actually is (a fixed number of particles, the Avogadro constant), why it's so large (because atoms are unimaginably tiny), how the mole links the number of particles to mass through relative mass, and how to convert between moles, number of particles, and mass. Once you see the mole as "a chemist's dozen," every mole calculation stops being scary. This is video 3.3 of my full Cambridge IGCSE 0620 chemistry series — built for understanding, not memorising.
