Chemistry

An aqueous ethylene glycol (HOCH2CH2OH, FW = 62.07 g/mol)solution with a mass of 207.9 mg is titrated with 48.9 mL of 0.0829M Ce4 in 4 M HClO4. The solution is held at 60°C for 15 minutes tooxidize the ethylene glycol to formic acid (HCO2H) and carbondioxide. The excess Ce4 is titrated with 11.07 mL of 0.0409 M Fe2to a ferroin end point. What is the mass percent of ethylene glycolin the unknown solution?
