The accompanying data (1.00-cm cells) were obtained for the spectrophotometric titration of 10.00 mL of Pd(II) with 2.44 x 10-4 M Nitroso R (0.W. Rollins and M. Oldham. Anal. Chern., 1971, 43, 262).
Calculate the concentration of the Pd( II) solution, given that the ligand-to-cation ratio in the colored product is 2: 1
