A 9.6286 g sample of a salt was analyzed for its iron content as follows: the entire sample was dissolved and diluted to a final volume of 182.4 mL. A 14.39 mL aliquot of the solution required 10.77 mL of a 0.05961 M potassium permanganate solution to reach at end point. A blank concentration of 0.07 mL was required. Calculate the % ( w / w ) Fe in the sample. Provide the answer to two places after the decimal.
