A sample of pure CaCO3 weighing 0.3677g is dissolved in hydrochloric acid and the solution diluted to 250.0ml in a volumetric flask. A 25.00ml aliquot requires 30.26ml of an EDTA solution for titration. Calculate a) the molarity of the EDTA solution; b) the number of grams Na2H2Y•2H2O (FW = 372.2) required to prepare 500.0ml of the solution.
