I know how to calculate the volume required each from 1 mol dm-3 CH3COOH and 1 mol dm-3 CH3COONa to prepare 100.0 ml of 0.1 M CH3COOH/ CH3COONa buffer with pH = 5

but this question is slightly different. How do I calculate the volume required each from 1 mol dm-3 CH3COOH and 1 mol dm-3 NaOH to prepare 100.0 ml of 0.1 M CH3COOH/ CH3COONa buffer with

pH = 5.

pKa of CH3COOH = 4.75
