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 = 43.2 ml

Molarity of standard base (NaOH) = 0.20 M

What is the molarity of the acid solution?

If a || b and e || f, what is the value of y ?
