A 25.0 mL aliquot of 0.0480 M EDTA was added to a 50.0 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 0.0330 M Ga³+ solution until all of the EDTA reacted, requiring 10.0 mL of the Ga³+ solution. What was the original concentration of the V3+ solution? [V³+] = M
