In an experiment, 10.0 ml of 0.040 M KMnO4 is added to 50.0 ml of a solution containing some unknown M of KMnO4 already. The absorbance of the unknown solution before the addition of the standard was 0.5622, and after the addition of the standard was 0.7822.
a. What is the value for e, if the pathlength, b, was 2.5 cm?
b. What was the concentration of KMnO4 in the original 50.0ml of the solution?
c. What are the T's of the 2 respective solutions?
