Problem- 1.3371 g of steel is dissolved and treated so that the Mn present is oxidized to MnO4-. The solution to 2.00 L and then shows an absorbance of 1.096. 50.0 mL of the solution is then mixed with 15.0 mL of 4.00 x 10^-4 M KMnO4 and the absorbance of the resuling solution is 1.097. what was % w/w Mn in the steel? (% w/w). FM of Mn is 54.938.
Any expert is able to provide answer for this problem in very short time
