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.
Lesson by Daniel Dulek, animation by Augenblick Studios.

This is such a good explanation. I’m doing HSC chemistry and one of the things I revisited was the definition of a mole. My prof is usually well versed on practically anything but when I asked him this there was a surprising doubt. Not because he didn’t know of course, but it was hard to translate to words. This does that beautifully

I feel it's relevant to mention that the reason the mole is so important is because it's the conversion factor between amu (the mass number on the periodic table) and grams. That's why a mol of water weighs 18.01 grams and a single molecule of water is 18.01 amu

He didn't mention about the relationship between the mole and the atomic weight. For those who couldn't understand why it's 6.02*10^23, let me tell you. Chemists made a so-called atomic weight. They decided that the atomic weight of a single Carbon atom, which has 6 protons and 6 neutrons, would be '12', and the rest of the atoms' weight would be decided by the relative weight of the Carbon. The atomic weight is pretty neat; almost every atom has a integer weight except a few (of course they are not perfect integers. They are very close to the integers, like 26.982; the atomic weight of the aluminium). If you take 6.02*10^23 numbers of an atom, there will be exactly 'the atomic weight of the atom' grams of the atom. For example, If you take 32 grams of an Oxygen atom, which has 16 atomic weight, there will be 2*6.02*10^23 numbers (=2 moles) of the Oxygen atoms.

the mole is defined so that one mole of hydrogen atoms (which weight 1u, atom mass unit) has a mass of 1 gram. Water has one oxygen atom (16u) and two hydrogen atoms (2u total) which adds up to 18u.

I wish my teachers of the difficult subjects in high school could have made learning fun and interesting like this. I never could understand the concept of a mole or Avagadro’s (sp?) number. I dropped chemistry because the teacher couldn’t explain it below the level of the smartest five students in the class and the textbook was worthless. I wanted to understand it so badly but I just couldn’t get it. On a lark, I was thinking about that today and decided to look it up. Forty-two years later, it finally makes sense to me, because it was simply explained. Thank you, TEDEd!

1. Because one wants to be precise, but not overly so. 10^23 is rounding it too much. A bit like rounding 60 to 100, when there's still 40 too many. 2. Comes from the word molecule, which means 'extremely small particle'.

It could have been more useful if you explained how they came up with the avogadro's number.

This video wouldn't have enlightened schoolkid-me to the concept or the thought-process behind "a mole" (Why/how Avogadro thought it up, how it is useful/applicable, and why it is significant). The furry-creature, doughnuts, post-mortem dancing and basketball analogies/anecdotes merely detract from the subject-matter.

+Aditya Mehendale I think it does a good job, I didn't get confused or distracted by the furry-creature or doughnuts, instead it put it in perspective.

+Aditya Mehendale The video isn't dedicated to explaining the mole's reasoning, but rather seeks to get a feel for how large it really is. The mole is significant because it allows us to convert from atomic mass to grams. 1 mole of any atom weighs its atomic mass but in grams. For example carbon's atomic mass is 12.011 atomic mass units. If you had a mole , or 6.02 * 10^23, of carbon atoms, it would weight 12.011 grams. This allows chemists to calculate aproximately how many particles of a substance they have based on the mass.

+Jed Nixon Thanks, I'm sure you mean well, but I was a schoolkid many many *many* years ago. What would have interested me, back then, is not *what* Avogadro's number is, to the 16th digit behind the decimal, but rather *how* Mr. Avogadro (with the limited resources available to him in his time) actually came to determine this number, what thought experiments he must have done to reason this out etc. What bothers me about this video is the presumption that the viewers would want the 'dumbed down' version of the story and the inane factoids about Avogadro's number (just like I would be when someone recites Pi to the 2000th place without having a clue about what Pi stands for). What also bothers me, is that at the daVinci museum in Florence, kids are forbidden to touch and play with (replicas of) daVinci's designs, being asked instead to look at animations on tablets - but that's another discussion ;). Free video on 'teh Interwebs' - can't complain much, right?

well Aditya Mehendale i agree with you but this is a channel who do mostly short video's "sadly", they are here to entertain us. And making a 2 hour long lecture with some "boring dry matrial" would scare off most, me included.
