II. Your calcium carbonate antacid tablet weighed 1.50 g. You added 25.00 mL of a 1.00 M solution of HCl. Then you titrated the excess HCl with 0.100 M NaOH. It took 14.33 mL to the endpoint. SHOW WORK! How many moles of HCl did you add initially? How many moles of NaOH did you use in the titration? How many moles of HCl were titrated (left over)?_
