A mixture of H(2)SO(4) and H(2)C(2)O(4) ...

A mixture of `H_(2)SO_(4)` and `H_(2)C_(2)O_(4)` (oxalic acid ) and some inert impurity weighing 3.185 g was dissolved in water and the solution made up to 1litre. 10 mL of this solution required 3 mL of 0.1 N NaOH for complete neutralization. In another experiment 100 mL of the same solution in hot condition required 4 mL of 0.02 M `KMnO_(4)` solution for complete reaction. The mass % of `H_(2)SO_(4)` in the mixture was:

A

40

B

50

C

60

D

80
