coffee. The average pure caffeine yield was 0.330% with a standard deviation of 0.179. This yield is slightly higher than the yield of this report because of the error that occurred during the experiment. A small amount of coffee from the first extraction was stuck in the nozzle of the separatory funnel so it was removed with a pipet and then decanted. This resulted in a loss of product. The average impure caffeine yield was found to be .948% with a standard
