The required volume of 0.10M NaOH solution that student will add is 20 mL.

<h3>How do we calculate the volume?</h3>

Volume of any solution which is required to prepare buffer will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

On putting values, we get

V₁ = (0.1)(20) / (0.1) = 20mL

Hence required volume of NaOH solution is 20mL.
