Atomic absorption spectroscopy was used with the method ofstandard additions to determine the concentration of cadmium in asample of an industrial waste stream. For the addition, 10.0 μL ofa 1000.0 μg/mL Cd standard was added to 10.0 mL of the unknownsolution. The results obtained are shown in the table. AbsorbanceReagent blank 0.028 Sample 0.480 Sample plus addition 0.887 What isthe concentration of the cadmium in the waste stream sample? c = μg / mL Later, the analyst learned that the blank was not truly areagent blank, but water. The absorbance of the actual reagentblank, is 0.062 . Calculate the cadmium concentration using the newinformation for the blank. c = μ g / mL Calculate the percent errorcaused by using water as the blank instead of the reagent blank.error: %
