The volume of titrant required for the titration would be 19.81 mL.
Since the burette was not filled to the zero mark during the titration and the level of base titrant was not filled to the 2.42 mL mark. As a result, the difference between the two values represents the total amount of titrant used in the titration.
therefore,
Volume of titrant after running titration - Volume of titrant before running titration = total titrant required for the titration
22.23 - 2.42 = 19.81 mL
What Exactly Is Titration?
Titration is a laboratory technique that uses a solution with known volume and concentration to determine the concentration of an unknown solution. Between the two solutions, an oxidation-reduction reaction or acid-base neutralization occurs, and the known quantities are used to calculate the unknown. The known concentration standard solution is referred to as the titrant or titrator, while the unknown concentration solution is referred to as the titrand or analyte.

The chemical formula for this compound is CaCl2.
If I remember correctly, it would be B. A very large amount of energy is produced from a tremendous mass.
