a) Analyte A in water sample was analyzed by atomic absorption spectroscopy method with a blank subtraction. The sample was diluted 20 times. The analytical signal (corrected value) for the sample analyzed was 0.39. What is the concentration of copper in the water sample? Express it in molar concentration. The calibration curve obtained for standard solutions and its equation is plotted below.
