  4. Stoichiometry • Mole – Mole Stoichiometry Conversions • Sample Problem • In a spacecraft, the carbon dioxide exhaled by astronauts can be removed by its reaction with lithium hydroxide, LiOH, according to the following chemical equation • How many moles of lithium hydroxide are required to react with 20 mol CO2, the average amount exhaled by a person each day? CO2(g) + 2LiOH(s) → Li2CO3(s) + H2O(l)

  5. Stoichiometry • Mole – Mole Stoichiometry Conversions • Sample Problem Solution • Given: amount of CO2 = 20 mol • Unknown: amount of LiOH (mol)

  8. Stoichiometry • Stoichiometry Conversions • Sample Problem • In photosynthesis, plants use energy from the sun to produce glucose, C6H12O6, and oxygen from the reaction of carbon dioxide and water • What mass, in grams, of glucose is produced when 3.00 mol of water react with carbon dioxide? 6CO2(g) + 6H2O(l) → C6H12O6(s) + 6O2(g)

  9. Stoichiometry • Stoichiometry Conversions • Sample Problem Solution • Given: amount of H2O = 3.00 mol • Unknown: mass of C6H12O6 produced (g) 90.1 g C6H12O6

  11. Stoichiometry • Stoichiometry Conversions • Sample Problem • The first step in the industrial manufacture of nitric acid is the catalytic oxidation of ammonia • The reaction is run using 824 g NH3 and excess oxygen. • How many moles of NO are formed? • How many moles of H2O are formed? NH3(g) + O2(g) → NO(g) + H2O(g) (unbalanced)

  12. Stoichiometry • Stoichiometry Conversions • Sample Problem Solution • Given: mass of NH3 = 824 g • Unknown: amount of NO produced (mol) amount of H2O produced (mol) 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g)
