How big is a mole? (Not the animal, the other one.)
The word "mole" suggests a small, furry burrowing animal to many. But in this lesson, we look at the concept of the mole in chemistry. Learn the incredible magnitude of the mole-- and how something so big can help us calculate the tiniest particles in the world. [Directed by Barbara Benas, narrated by Daniel Dulek].
