  1. Chapter 8: The Mole – Part 1

  2. What is Avogadro’s favorite saying from American History?

  3. The Mole • A mole is Avogadro’s number of particles, that is 6.02 × 1023 particles. • 1 mol = Avogadro’s Number = 6.02 × 1023 particles

  4. How Big is a Mole? • Where would you need to go to see 1 mole of rice grains?

  5. How Big is a Mole? • 1 mole of rice grains is more than the number of rice grown since the beginning of time?

  6. How Big is a Mole? • The worlds fastest supercomputer can count the world’s population in ¼ second. How long would it take this computer to count to 1 mole?

  7. How Big is a Mole? • The worlds fastest supercomputer can count the world’s population in ¼ second. It would take this computer 1.9 million years to count to 1 mole?

  8. How Big is a Mole? One mole of marbles would cover the entire Earth (oceans included) for a depth of three miles. One mole of $100 bills stacked one on top of another would reach from the Sun to Pluto and back 7.5 million times. It would take light 9500 years to travel from the bottom to the top of a stack of 1 mole of $100 bills.

  9. How Big is a Mole? • Where would you need to go to see 1 mole of water.

  12. What is the mass in grams exactly 1 mole of water? • 1.66 x 10-24 g/amu 1 mol H2O

  13. What is the mass in grams exactly 1 mole of water? • 1.66 x 10-24 g/amu 1 mol H2O 6.02 x 1023 H2O molecules mol H2O

  14. What is the mass in grams exactly 1 mole of water? • 1.66 x 10-24 g/amu 1 mol H2O 6.02 x 1023 H2O molecules 18.0 amu mol H2O molecule H2O

  15. What is the mass in grams exactly 1 mole of water? • 1.66 x 10-24 g/amu 1 mol H2O 6.02 x 1023 H2O molecules 18.0 amu 1.66 x 10-24 g mol H2O molecule H2O amu

  16. What is the mass in grams exactly 1 mole of water? • 1.66 x 10-24 g/amu 1 mol H2O 6.02 x 1023 H2O molecules 18.0 amu 1.66 x 10-24 g mol H2O molecule H2O amu = 18.0 g

  17. 1 mol H2O = 18.0g • This is the gram formula mass of water. • This is the molar mass of water. • The gram formula mass (molar mass) is the molecular mass of the substance in grams.

  18. What is the mass of 1 mol sucrose (C12H22O11)

  19. 1 mol sucrose (C12H22O11) = 342.0g • 12 x 12.0 = 144.0 • 22 x 1.0 = 22.0 • 11 x 16.0 = 176.0 gfm = 342.0 g

  20. Why 6.02 x 1023 • How did scientists come up with such a random number for the mole? • It’s really not random at all. It is really just based on a ratio that you have already used. • 1.66 x 10-24 g/amu.

  21. Why 6.02 x 1023 • Let us assume that we are attempting to determine the number of particles in a mole. In other words we do not know that it is 6.02 x 1023. • How many atoms are in exactly one mole of carbon?

  22. Why 6.02 x 1023 • How many atoms are in exactly one mole of carbon? 1 mol C
