Chapter 4 Lecture Outline A. Reaction Stoichiometry/Limiting Reagent/Theoretical Yield/Actual Yield 2 N 2 (g) + 5 O 2 (g) 2 N 2 O 5 (g) 1. What mass of O 2 (g) is required to react exactly with a specified mass of N 2 (g)? 2. What mass of N 2 O 5 (g) is formed by complete reaction of a specified mass of N 2 (g)? 3. Given a specified yield of N 2 O 5 (g), calculate the actual percent yield of the reaction. 4. When a specified mixture of N 2 (g) and O 2 (g) are reacted, determine which compound is the limiting reagent and the maximum mass of N 2 O 5 (g) formed by complete reaction. B. Molarity and Solution Stoichiometry 1. When a specified mass of MgCl 2 is dissolved in water to give a specified volume of solution, what is the molarity of that solution? 2. What is the molarity of chloride ion in that same solution? 3. What volume of that solution would contain a specified mass of MgCl 2 ? 4. What volume of that solution is required to give a specified volume having a
