What number of grams of sodium benzoate is necessary to mix with 10 liters of 0.15M benzoic acid to produce a buffered solution of pH equal to 4.8?(Ka=6.5x10-5).eport Abuse. pKa = - log Ka = 4.2 4.8 = 4.2 + log [C6H5COO-]/ 0.15 10 ^ 0.6 = 4.0 = [C6H5COO-]/ 0.15 [C6H5COO-]= 0.60 M moles sodium benzoate needed = 0.60 M x 10 L = 6.0 mass C6H5COONa = 6.0 mol x 144.11 g/mol= 864.6 g.
