But in this lesson, we look at the concept of the mole in chemistry. One mole of red blood cells is more red blood cells than exist in every human on earth right now. What if all the sea water became fresh water? A mole of aluminum is about 26 grams. These two statements seem contradictory to me: “If you had a mole of basketballs, you could create a new planet the size of the Earth!”, “A mole of turkeys could form sixteen earths.”. Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The magnitude of the number 6.02×1023 is challenging to imagine. A way to think about the relative size of a mole? But to really appreciate how many molecules are in a mole it helps to think about things we can see. Indeed very interesting to learn this… Leaves a last long impression of what a mole is… I wish i would have a mole of pennies!!!! A mole of cereal boxes stacked end to end would reach from the Sun to Pluto 7.5 million times. The unit “mole” is used in chemistry as a counting unit for measuring the amount of something. But in this lesson, we look at the concept of the mole in chemistry. Today’s mole is a unit — one invented by a man named Avogadro. Want a daily email of lesson plans that span all subjects and age groups? What would a mole of fuzzy moles look like? Because the mole contains so many units, they’re most often used in chemistry is a way of measuring really really small things like atoms or molecules. Sorry, your blog cannot share posts by email. The goal of this project is to understand just how big a mole is. Basically, that's why this particular unit was invented. Really, a mole is just a group of objects. Thankfully, there’s no chemistry equation in the world that calls for that many mammals. You can have a mole of molecules or people or cheeseburgers. Well, the pile of animals would weigh a little over half of the mass of our moon. Your name and responses will be shared with TED Ed. Only students who are 13 years of age or older can save work on TED-Ed Lessons. In short, for particles, 1 mol = 6.02214076×10 . One mole of atoms contains 6 x 1023 atoms, no matter what element it is. Moles are no different. A mole of carbon atoms is 6.02x10 23 carbon atoms. If you received a mole of pennies on the day you were born, and spent a million dollars a second until you died at 100, you’d still have over 99.99% of your money in the bank. Okay, so now that we know why a mole has 6.02 x 1023 things in it, what can we do with that information? Create and share a new lesson based on this one. So a mole of water is 6.02 x 1023 molecules of water, which works out to be about 18 grams, or 18 mL. Are you an educator or animator interested in creating a TED-Ed Animation? How to build your confidence— and spark it in others - Brittany Packnett. That’s 602,000,000,000,000,000,000,000 things. Learn the incredible magnitude of the mole--and how something so big can help us calculate the tiniest particles in the world. 5 steps to help you figure out your passion. Well, the pile of animals would weigh a little over half of the mass of our moon. To track your work across TED-Ed over time, Register or Login instead.

A mole of a substance or a mole of particles is defined as exactly 6.02214076×10 particles, which may be atoms, molecules, ions, or electrons. The word “mole” suggests a small, furry burrowing animal to many. This is a very large number: it is 6 with 23 zeros after it. Because the mole contains so many units, they’re most often used in chemistry is a way of measuring really really small things like atoms or molecules. You can think of “a mole” the same way you think of “a dozen.” You’re probably familiar with a dozen eggs, or chickens or planets. There are about 20 species of fuzzy moles (the kind that crawl around on the ground), and one kind of mole that might appear on your face, but today is a day for celebrating a different kind of mole. Click Register if you need to create a free TED-Ed account. The word “mole” suggests a small, furry burrowing animal to many. A mole is defined as the amount of substance which contains as many as elementary particles as present in 12 g of carbon 12 isotope. Chemists think of moles or atoms like you and I think of a dozen eggs – we add them to recipes, order them from the store and calculate what we need based on how many we have.
