Answer:
The initial volume and molarity of the HCl are 12.3 mL and 0.22 M, respectively.
Explanation:
The volume of LiOH used is 18.0 mL. To find the concentration of LiOH, you can use the formula M1V1 = M2V2, where M1 is the molarity of the first solution, V1 is the volume of the first solution, M2 is the molarity of the second solution, and V2 is the volume of the second solution. Plugging in the values, you can calculate the concentration of LiOH.
