A solution was made in a 200.00 mL volumetric flask consisting of 18.00 mL of 2.125 M HCl and 0.4104 grams of CaCO3, followed by adding enough water to bring the final volume up to the mark on the flask. A 15.00 mL sample of the solution was titrated with 0.1111 M NaOH to the equivalence point. How many mL of NaOH are used
