Question

Using the Absorbance (0.455) of your Unknown SCN- solution and the slope (3163.9) from your Calibration Curve, calculate the concentration of SCN- in the solution created from 5.0 mL 0.200 M Fe(NO3)3, 40.0 mL H2O and 5.0 mL SCN-. How would I calculate?

A = ebc where e is the molar absorptivity = slope of the line.


0.455 = 3163.9*c
Calculate c.
