Academics

You measure 2.34 grams of potassium dichromate K₂Cr₂O₇into a volumetric flask. You dilute the potassium dichromate K₂Cr₂O₇ with H₂O to a volume of 250 mili litres. It takes 35.7 mL of this solution to titrate 17.8 mL of a solution of Sodium oxalate, or disodium oxalate in the presence of excess acid. Determine the concentration of the original Na₂C₂O₄ solution?
