The amount of 15 (aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2S₂O3(aq) +15(aq) → SO2 (aq) +31-(aq) Given that it requires 27.8 mL of 0.200 M Na₂S₂O₂(aq) to titrate a 20.0 mL sample of 15 (aq), calculate the molarity of 15 (aq) in the solution. [13] = 0.278 M
