  1. “Good News & Bad News About Chemistry, Plus Counting Without Counting” • http://www.chemistryland.com/CHM130W/07-Mole/Mole.htm

  2. The Mole The Mole - a unit used to count small particles such as atoms • Important Facts: The standard for the mole is the number of atoms in 12 grams of Carbon-12 • This number is 6.023 x1023 and is known as Avogadro’s number

  3. Avogadro

  4. Avogadro’s Number…Give him a call(How to lose a date in 3 seconds)

  5. 1 Mole is 602,300,000,000,000,000,000,000 of something

  6. Units For Counting Dozen = Ream =

  7. How Many… • A dozen eggs is _____ eggs. • A dozen elephants is _____ elephants. • A dozen cars is _____ cars. • A dozen flying monkeys is _____ flying monkeys

  8. How Many… • A mole of eggs is _____ eggs. • A mole of elephants is _____ elephants. • A mole of cars is _____ cars. • A mole of flying monkeys is _____ flying monkeys • A mole of atoms is _______ atoms. • A mole of molecules is ________ molecules. • A mole of dollar bills is ________ dollar bills. • A mole of particles is ________ particles. • A mole of anything is ___________.

  9. The number is the same but is the mass? • Is the mass of a dozen eggs the same as the mass of a dozen elephants? • Is mass of a mole of carbon atoms the same as the mass of a mole of hydrogen atoms?

  10. Proof That Chemists Have No Life

  11. Avocado’s Number?

  12. That’s not avocado’s number

  13. The Elusive “Guacamol”

  14. A “Guacamol” Party

  15. Useful Conversions Factors 1 mole = 6.022 x 1023 particles 1 mole = gfm (molar mass) 1 mole = 22.4 Liters (@STP)
