Concentration of thiosulfate, molarity

Calculate concentration of thiosulfate ion, S2O3^2-, when 1.00 mL of .00500 M Na2S2o3 are added to experiment.

Solution Preview

1 mole of Na2S2O3 in solution will dissociate to give 2moles of Na+ ions and one mole of S2O32- ions as follows,

Na2S2O3 -------→ 2Na+ + S2O32-

Now given molarity of Na2S2O3 = ...
