A solution containing Cu2+ is analyzed by atomic absorption and gives an absorbance of 0.01000 units. The solution is spiked to increase the Cu2+ concentration by 2.000 mg/L and then gives an absorbance of 0.01613 units. (a) What is the concentration of Cu2+ in the solution (mg/L)? (b) The 1.000 mg/L solution of Cu2+ alone gave an absorbance of 0.00408 units; was the standard addition needed? Yes or No
