Understanding Moles and Mass: Conversion Factors for Aluminum and Aspartame in Diet Cola

This chapter explores the concept of moles and mass, using aluminum and aspartame as examples. It outlines the conversion factors needed to convert moles of aluminum (Al) to grams, demonstrating the calculation for 3.62 moles of Al. Additionally, it discusses aspartame's molecular weight and how to determine the number of moles present in 200 mg from a can of diet cola. The chapter also examines the total number of molecules and individual atoms (carbon, hydrogen, nitrogen, and oxygen) found in aspartame, enhancing understanding of molecular composition.

  1. Chapter 8 The Mole Part 2

  2. 1 Mole of Particles What are the conversion factors?

  3. 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

  4. 1 mole Al = 27.0 g Al

  5. 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

  6. 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

  7. 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

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

  9. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 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

  10. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 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 mg

  11. A can of diet cola contains about 200.0 mg of the artificial sweetener aspartame (Nutra-Sweet) formula C14H18N2O5 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 294g

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

  13. How many aspartame molecules would you consume for each can of diet cola that you drank? 6.803 x 10-4 mol C14H18N2O5 6.02 x 1023 molecules mol = 4.10 x 1020C14H18N2O5 molecules

  14. 4.10 x 1020 C14H18N2O5 molecules • How many carbon atoms? • How many hydrogen atoms? • How many nitrogen atoms? • How many oxygen atoms? • How many total atoms?
