The absorbance of a 6.3x10^-5M solution of an iron complex was measured to be 0.328 at the optimum wavelength. A second solution of the iron complex has an absorbance of 0.833 measured under identical conditions. What is the molarity of the complex in the SECOND SOLUTION?
College Chemistry Lab -
Absorbance = kC
Plug in A and C from the first run and calculate k.
Use k and absorbance of second run to calculate C for second sample.
