An aqueous ethylene glycol (HOCH2CH2OH, FW = 62.07 g/mol) solution with a mass of 262.3 mg is titrated with 62.7 mL of 0.0851 M Ce4 in 4 M HClO4. The solution is held at 60°C for 15 minutes to oxidize the ethylene glycol to formic acid (HCO2H) and carbon dioxide. The excess Ce4 is titrated with 12.39 mL of 0.0493 M Fe2 to a ferroin end point. What is the mass percent of ethylene glycol in the unknown solution?
