TED-Ed: How big is a mole? (Not the animal, the other one.) - Daniel Dulek

The video tutorial introduces the concept of the mole in chemistry, explaining its significance in counting extremely small particles like atoms and molecules. It discusses Avogadro's hypothesis, which laid the foundation for the atomic theory, and introduces Avogadro's number, 6.02 x 10^23, as a way to quantify large numbers of particles. The tutorial uses visual analogies, such as a mole of donuts or basketballs, to help viewers grasp the enormity of a mole. Finally, it explains how chemists use the mole in practical applications, similar to how we use units like pounds or dozens in everyday life.
