In the titration described in the previous problem, EDTA binds calcium ions with 1:1
stoichiometry. If you begin the titration with a beaker containing 247 mL of CaCl₂ solution, and observe a color
change after adding a total of 36.8 mL of 1.69 M EDTA solution, what was the molar concentration of the initial CaCl2 solution? (Decimal place, not scientific notation, using 3 significant figures)
