Project Experiment: Identification of a Cobalt Amine Halide Complex To calculate percent yield, you will need to decide which compound you made first % Halide in Synthesized Compound: Trial #1 40.836 Average Value: 40.29% Trial #2 39.745 % Cobalt in Synthesized Compound: Trial #1 22.97% Best Average Value: 22.87 Trial #2 22.747 Here are the possible unknowns: Complex CO(NH3)4]C13 Co(NH3)s]Cl3 CO(NH3).]C13 CO(NH3)4]Br3 CO(NH3)s]Br Co(NH3)]Br MW 233.42 250.45 267.48 366.43 383.63 400.63 % Cl or Br % Co 45.56 25.25 42.46 23.53 39.76 22.03 65.38 16.07 62.48 15.36 59.83 14.71 % NH 29.19 34.01 38.21 18.55 22.16 25.46 Now, take the number of moles of the cobalt source you used (ex CoBrz-6H30). Then take the number of moles of the complex you got, by using the molecular weight of your "guess" and the number of grams you isolated. The theoretical is the number of moles of the cobalt source, and the actual is the number of moles of the complex you got. Percent yield (actual/theoretical) * 100% Percent yield Calculation: 48
