What amount of solution propanoate should be added to one litre of an aqueous solution containing `0.02` mole of propanoic acid (`K_(a)=1.0xx10^(-5)` at `25^(@)C`) to obtain a buffer solution of `pH 6`

How much moles of sodium propionate should be added to 1L of an aqueous solution containing 0.020 mol of propionic acid to obtain a buffer solution of pH 4.75 ? What will be the pH if 0.010 mol of HCI is dissolved in the above buffer solution. Compare the last pH value with the pH of 0.010 M HCI solution. Dissociation constant of propionic acid, K_(a) , at 25^(@)C is 1.34 xx 10^(-5) .
