What volume of 0.2 M NaOH solution is needed for complete neutralisation of 0.49 gm orthophosphoric acid

Volume of 0.1 M NaOH needed for the neutralisation of 20 ml of 0.05 M oxalic acid is :

In the titration of a certain H_(2)SO_(4) solution, 60 mL of 5.0 M NaOH solution was used to completely neutralise 75 mL of the acid. The molarity of the acid solution may be expressed as
