A copper (II) sulfate solution of unknown concentration is placed in a colorimeter and an absorbance reading of 0.46 is recorded. Using the same solution cell, a 0.055 M of copper (I) sulfate gives an absorbance reading of 0.34. What is the concentration of the first solution? A. 0.074 mol mol dm-3 B. 0.041 mol dm3 O C.0.35 mol dm3 D. 8.60 x10-3 mol dm 3
