A 25.0 mL aliquot of 0.0630 M EDTA was added to a 30.0 mL solution containing an unknown concentration of V3+. All of the V3+ present in the solution formed a complex with EDTA, leaving an excess of EDTA in solution. This solution was back-titrated with a 0.0360 M Ga3+ solution until all of the EDTA reacted, requiring 13.0 mL of the Ga3+ solution. What was the original concentration of the V3+ solution?
