A20ml sample of hcl was titrated with the 0.0220 m naoh. to reach the endpoint required 23.72 ml of the naoh. calculate the molarity of hcl

Molarity of HCl=0.026092M

Explanation:

The equation for the reaction is;

HCl + NaOH ⇒ NaCl + H2O

Using the formular,    ..........equ1

where is the concentration of Acid,

          is volume of acid

          is concentration of the base

          is volume of the base

          nA is the number of moles of Acid

          nB is number of moles of base

nA = 1,    nB=1 , , ,

we will input these values into equation1 to solve for
