You have a solution of approximately 0.196 molL-1 NaOH, but you need to confirm its concentration by titration. You have a solution of 3.92 molL-1 HCl. The HCl is too concentrated, you will need to dilute it.
Good practice says that you should have approximately 20mL of HCl run from the burette to the 20mL of NaOH in the flask. Show by calculation and reason the dilution of HCl that you will need to achieve to be carrying out good practice.
