Plot the values of RG Absorbance versus concentration on a spreadsheet or a
programmable calculator, and carefully determine the slope of the best straight line fit 65 through the data. The slope values for GG, GR, RG, and RR must be accurately
determined because they will enable you to solve for the unknown concentration of your
mixture of the two cobalt complexes. Enter the value of the slope of A vs.C. This is your
effective extinction coefficient for RG.
Now let's collect the data needed for the determination of the RR effective extinction
coefficient. The absorbance values should have a value between 0 and 1. Please enter the
four values of the RR absorbance measurement in corresponding order of solution
concentration (high concentration to low concentration; values of absorbance will be
running in the same sense, high absorbance to low absorbance and expressed to three
