To determine the molar concentration of a metal ion in a solution of unknown concentration, a student fırst made five standard solutions that contain the metal ion of interest and measured the absorbance of each solution in a spectrophotometer at its åmax- A calibration curve was obtained that had an equation of y = 5.747 x + 0.013 Next, the student pipetted 15.0 mL of the initial solution of unknown concentration into a 100.0 mL volumetric flask, and filled the flask with deionized water to the line. The absorbance of this final diluted solution was found to be A = 0.226 at Amax- The color of the original and diluted solution was blue. What is the molarity of the original solution, as well approximate Amax for this metal ion? Amax = 599 nm and concentration is 0.247 M %3D Amax = 457 nm and concentration is 0.247 M %3D i max = 457 nm and concentration is 0.0371 M a max = 599 nm and concentration is 0.0371 M %3D Amax = 599 nm and concentration is 0.00557 M %3D
