how did u get that can you please explain the steps

To solve this, you require the Henderson-Hasselbach equation: pH = pKa + log(conc.base/conc. acid)
You have pH and pKa, so plug in the numbers, and solve for the ratio of Base/acid. With some algebra, you can then figure out the volume amounts of each species.

what are the numbers for Conjugate acid and conjugate base
