An as received sample of the salt Sn3(PO4)2 (546.0727) weighing 5.0550 g was dissolved in water. The sample was treated to completely reduce all the tin to Sn2+. This solution was then titrated with standard 0.1133M KMnO4 (158.03). 40.00 mL of the standard KMnO4 solution was used in the titration to reach the equivalence point. What is % Sn3(PO4)2 in sample?
