  1. Chapter 8 The Mole Part 2

  2. What is Avogadro’s Favorite Music

  3. What is Avogadro’s Favorite Music a

  4. Aluminum is often used for the structure of light-weight bicycle frames. How many grams of Al are in 3.62 moles of Al? Converting Moles and Grams a

  5. 1 mole Al = 27.0 g Al

  6. What are the conversion factors? • 1 mole Al = 27.0 g Al

  7. What are the conversion factors? • 1 mole Al = 27.0 g Al • 27.0g Al or 1 mol Al • 1 mol Al 27.0 g Al

  8. What are the conversion factors? • 1 mole Al = 27.0 g Al • 27.0g Al or 1 mol Al • 1 mol Al 27.0 g Al Aluminum is often used for the structure of light-weight bicycle frames. How many grams of Al are in 3.62 moles of Al?

  9. 1 mole Al = 27.0 g Al • Conversion factors for Al • 27.0g Al or 1 mol Al • 1 mol Al 27.0 g Al • 3.62 moles Al

  10. 1 mole Al = 27.0 g Al • Conversion factors for Al • 27.0g Al or 1 mol Al • 1 mol Al 27.0 g Al • 3.62 moles Al 27.0 g Al • 1 mole Al = 97.7g Al

  11. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 . It is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola?

  12. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 . It is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola? 200.0 mg

  13. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 . It is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola? 200.0 mg 0.001g mg

  14. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 . It is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola? 14(12.0) + 18(1.0) + 2(14.0) + 5(16.0) = 294.0 g/mol 200.0 mg 0.001g mol mg g

  15. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 . It is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola? 14(12.0) + 18(1.0) + 2(14.0) + 5(16.0) = 294g/mol 200.0 mg 0.001g mol 6.803 x 10-4 mol C14H18N2O5 mg 294.0 g

  16. How many aspartame molecules would you consume for each can of diet cola that you drank?
