Part 4: Percent Yield 4. Assuming the mass of the filter paper in your experiment was the same as in the video: a. Determine the mass of the filter paper plus the copper produced, assuming a percent yield of 68% copper. b. Show all your work. Part 5: More thinking like a Chemist: Molarity 5. A solution of a dissolved substance will have a certain concentration of dissolved substances. Molarity is a measure of the concentration of a solute in a solution (Section 6.3). a. Define the concentration unit molarity and explain how it is calculated. b. Copper (1) chloride dihydrate was initially dissolved in water. Given the volume of water used in the experiment, and assuming the volume of the resulting solution is the same as the water, calculate the molarity of the copper(II) chloride dihydrate after dissolving. c. Calculate the molarity of the individual copper(II) ions in the solution after dissolving, but before reaction. d. Calculate the molarity of the individual chloride ions in the solution before reaction. Learn more in the article: Helmenstine, Todd. (2020, August 28). Molar Concentration of lons Example Problem. Chemistry is all about keeping track of everything in a solution before...and after the reaction. Now that you know the mass of copper created and the grams of excess reactant remaining: e. Calculate the molarity of the chloride ions in solution after the reaction was completed, but before filtration. Explain your answer and compare to your answer to 5d. f. Calculate the molarity of the copper(II) ions in solution after the reaction was completed. g. To continue this analysis, what about the water molecules that were locked in the solid hydrate? When the hydrate initially dissolved, the water molecules tied up in the hydrate were freed to mix with the rest of the added water. Calculate the number of water molecules set free after the copper(II) chloride dihydrate dissolved. 2
