he sulfate in 266.5 mg sample was precipitated as BaSO4 by addition of 27.00 mL of 0.0340 M BaCl2. The precipitate was removed by filtration and the remaining BaCl2 consumed 34.2 mL of 0.0200 M EDTA for titration to the end point. (All 1:1 ratio) Calculate the % SO3 in the sample. (MW of SO3 is 80.06 g/mol)
