A spectrophotometer was calibrated with a 7.236 x 10-4 M (in Cu) Cu-neocuproine solution. This calibration was carried out in a 1.00 cm cell, and yielded an absorbance of 0.2680 AU. An unknown was then analyzed in this same spectrophotometer, but using a 2.50 cm cell. If the absorbance of the unknown was 0.3700 AU, what is the Cu concentration? M Submit Answer
