A stock solution of analyte is made by dissolving 34.83 mg of copper (II) acetate hexahydrate(fw = 289.73 g/mol) in 25.00 mL of water. A second stock solution of internal standard is madeby dissolving 28.43 mg of germanium (I) acetate (fw = 190.74 g/mol) into 25.00 mL of water.These solutions are used to make a series of standards for ﬂame atomic absorption analysiscalibration. The standard solutions (each 10.00 mL total volume) should have the followingconcentrations of copper: 10.00; 25.00; 50.00; 100.0; and 200.0 μM. Each calibration solutionshould also contain 50.00 μM of germanium. What is the analyte stock solution concentration? What is the internal standard stocksolution concentration?Complete this table.
