Questiоn ties tо questiоn-6 A 0.3205 g sаmple of CаCO3 wаs dissolved in HCl and the resulting solution was diluted to 250.00 mL in a volumetric flask.  From this volumetric flask, a sample of 25.0 mL  was obtained and titrated against EDTA. A 18.75 mL of EDTA was utilized to reach the end point (Eriochrome Black T used as the indicator) What is the concentration of EDTA solution? Hint: Moles = moles of EDTA / volume of EDTA in Liters.
