Yes, It is important to know the volume of Unknown acid or base to be titrated.

Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.

M₁V₁/n₁ = M₂V₂/n₂

YES

Explanation:

Titration is an analytical method or technique which is used to determine the concentration of an unknown solution, called analyte; by using a solution of known volume and concentration, called titrant.

In this method, the volume of the titrant used to neutralize the given analyte is noted and then the concentration of the unknown solution or the analyte is calculated by using the following equation:

$C_{titrant}\cdot V_{titrant} = C_{analyte}\cdot V_{analyte}$

Here, $C_{titrant}$ is the known concentration of the titrant

$C_{analyte}$ is the unknown concentration of the analyte

$V_{titrant}$ is the volume of the titrant used during the titration

$V_{analyte}$ is the known volume of the analyte

Therefore, in order to determine the concentration of the unknown solution or the analyte, the exact volume taken should be known.
