Introduction to Moles

Published on April 23, 2014 by

A mole is like a dozen. It is a name for a specific number of things. There are 12 things in a dozen, and 602 hexillion things in a mole. We'll talk about what moles are and why they are important. We will see how to abbreviate the mole number (Avogadro's number) using scientific notation, and we'll see how giant this number is.

    Omg thank you so much I love this vid.i am going this for my exam tmr but I’m still not understanding this.after watching this fantastic vid I know much more about moles.

  • Bowser Jjumetroid 3 years ago

    7:17 — Actually, the donuts would reach to the Sun and back to Earth >84 billion times. They would reach to the Sun, not going back to Earth, >168 billion times, closer to 200 billion as you say.

    Well, based on my calculations anyways.

  • Bowser Jjumetroid 3 years ago

    6:14 — Well, lets do the math: The radius of a jelly bean is approx 0.75 cm. I turn that into circumference, meaning (C = r(0.75) x 2 x 3.14(pi) = 4.71 cm in circumference). Then, plug in Avogadro’s Number (4.71 x (6.02 x 10^23) = (2.84 x 10^24 cm)).

    That is 2.84 × 10^19 kilometers in circumference, AKA >28 quintillion km!

    Now, the circumference of the Earth is (C = r(6,371 km) x 2 x π) = 40,075 km.

    This means (2.84 x 10^19)/40,075 = (7.09 x 10^14 km | 709 trillion km)

    In other words, one mole (6.02 x 10^23) of jelly beans (4.71 cm in circumference) is 709 trillion times bigger in circumference than Earth’s circumference.

    Did I make a mistake? I probably did considering the astronomical number.

    • Bowser Jjumetroid 3 years ago

      In diameter, one mole of jelly beans would be >1 quadrillion times bigger then Earth’s diameter.

      I still don’t know if I’m correct or not. Considering the massive number, I’m probably wrong.

  • ANOTRI KUMAR 3 years ago

    In ncert class 9 book it is written that 1 mole = 6.022 multiplied by 10 power 23 but sir why do you use 6.02 multiplied by 10 power 23

  • Amelia Sheriff 3 years ago

    someone please help, I am very confuse here. It’s said that for examplea single Carbon 12- atom has 6 photons and 6 neurons, making a mass of 12 o 12 of a single atom. Than a mole of carbon atoms has a mass of 12.011 which is 6 protons and it’s isotopes? How can a mole of atoms has the same mass

  • Amelia Sheriff 3 years ago

    as a single atom ?

  • Andrew Weng 3 years ago

    Hey Tyler, just personally I always thought you were the best Chemistry YouTuber out there. I do go too fast in my videos, but yours are perfect for taking it slower and being clearer (students need to realise we only have around 200min a week to get a lot covered including labs). Your videos are better than mine, and better than Hank Green, Bozeman and Khan Academy. Well done. I’ll do up a video to send my subscribers over to this channel!

  • Mihir Bendre 3 years ago

    Okay, I have a question!
    We all know that a mole has 6.02E23 atoms or molecules or anything, and we were told that it’s how many atoms are in a 12 g of C12, but for Avogadro to convert amu to g to # of atoms, he would have needed the conversion 1.99E-23 amu per gram. The math makes sense when you get 6.02E23 atoms, but how did Avogadro come up with the amu to g conversion?

    It still does not make sense to me that at the same temp and pressure – if 2 different gases (say o2 and Helium) occupy the same volume then there are the same number of constituent atoms in the volume despite the the mass being different for each different atom?

    Tyler DeWitt did a 8/10 job i think Tyler could improve in his explaination for the diameter and circumference of 1 single atom physical appearence regarding the size then based on the density and the volume you can calculate an estimate of how many atoms are in a given chalk like powdered rather than what looks like chalked powered lacking visual demonstration for an atom’s appearence is what you need to show

  • Elizabeth Rouse 2 years ago

    Tyler, I am older and have gone back to school. I specifically wanted the “in person” experience and now the pandemic has taken us all online and it’s my first class in 25 years and in a TOTALLY different field than I have been in. We are so challenged with technology failing and being unable to ask questions or do labs. I get really overwhelmed. My teacher tries but I am unable to absorb the material the way he teaches it. He makes it even more foreign. Then I find your vids…and the way you get so thrilled sharing science with us…and your anticipation of what our questions would be…and the insight to remind us of the building blocks leading to your topic….and I’m just SO VERY grateful for you and the extensive vids you have produced. I would be failing instead of making A’s if it weren’t for you. Thank you for the clarity and love you put into each one. Thank you for making my life SO much more…..MORE. Blessings on your punkin’ head! (PS. I subscribed )

    When amadeo Avogadro proved that there are so many molecules in a mole, the science community laughed at him. 100 yrs later, 2 guys proved that he was right, but avogadro never received credits because he was already dead. Even today his named is forever known.
