A mixture contaning 0.05 moleof `K_(2)Cr_(2)O_(7) and 0.02 "mole of" KMnO_(4)` was treated eoith excess of KI in acidic medium. The liberated iodine required `1.0L "of" Na_(2)S_(2)O_(3)` solution for titration. Concentration of `Na_(2)S_(2)O_(3)` solution was:

`0.4 molL^(-1)`

`0.20 molL^(-1)`

`0.25 molL^(-1)`
