Repeats of 12.64 mL samples of a 0.2937 M primary standard zinc ion solution were titrated with an EDTA solution of unknown molarity by the method associated with the experiment. The mean blank-corrected titration volumes was 14.31 mL. Calculate the molarity (M) of the EDTA solution. State the value to four places after the decimal place and without units. The reaction stoichiometrybetween zinc and EDTA ie 1:1
