The following data were collected at the endpoint of a titration performed to find the molarity of an HCl solution:
Volume of acid (HCl) used = 14.4 mL; Volume of base (NaOH) used = 22.4 mL;
Molarity of standard base (NaOH) = 0.200 M;
What is the molarity of the acid solution?

A. 1.6 M
B. 0.64 M
C. 0.31M
