A 21.524 g paint sample was analyzed for barium (Ba2+, MW = 137.327 g/mole) by an EDTA back titration: Ba2+(aq) + Y4–(aq) à BaY2–(aq). The sample was dissolved in acid and sufficient water was added to produce a volume of 100 mL. 10.00 mL of this concentrated solution was diluted to a volume of 50.00 mL. 25.00 mL of the diluted solution was treated with 33.95 mL of excess 0.09456 M EDTA. The excess EDTA was titrated to the endpoint...
