A substance has an extinction coefficient of 5 x 10^5 L cm^-1 mol^-1. A concentrated solution of this substance has an absorbance too high to measure. You dilute 1 ml of this solution to 25 ml with distilled water; the measured absorbance is 0.2. What is the concentration of the original concentrated solution?
