A 25.0-mL solution of 0.0670 M EDTA was added to a 34.0-mL sample containing an unknown concentration of V3 . All V3 present formed a complex, leaving excess EDTA in solution. This solution was back-titrated with a 0.0440 M Ga3 solution until all the EDTA reacted, requiring 12.0 mL of the Ga3 solution. What was the original concentration of the V3 solution?
