Copper was determined in an alloy sample by UV-visible spectrophotometry. The standard addition method was used. When exactly 5.0 mL of 1.00 g/L Cu standard solution was added to 100.0 mL of the sample solution, the blank-corrected absorption changed from 0.26 to 0.60. Calculate the concentration of Ču in the sample solution assuming the absorbance was directly proportional to the analyte concentration. A. 0.35 g/L B. 0.26 g/L C. 0.60 g/L D. 1.3 g/L E. 3.0 g/L

0.1040 g of a solid sample containing copper was dissolved by acid and transferred to a 250.00 mL volumetric flask and volume was made up with distilled water. The solution was then diluted by a factor of 20. The final solution was analyzed by atomic absorption spectrophotometry and the concentration was found be 3.109 ppm, What is the weight percentage of copper in the original solid sample? Keep four significant figures in your final answer. Do not try to include the "%" in your answer. e.g. if your final answer is 10.01%, only write 10.01 in the box.
