The volume of water which must be added to `0.4 dm^(3)` of 0.25 N oxalic acid in order to make it exactly decinormal is :

22.7 mL of (N/10) Na_(2)CO_(3) solution neutralises 10.2 mL of a dilute H_(2)SO_(4) solution. The volume of water that must be added to 400 mL of this H_(2)SO_(4) solution in order to make it exactly N/10.
