A 250.0 mL sample of a 0.20M `Cr^(3+)` is electrolysed with a current of 96.5 A. If the remaining `[Cr^(3+)]` is 0.1 M, the duration of process is:

A 500mL sample of a 0.1M Cr^(3+) is electrolyzed with a current of 96.5A . If the remaining [Cr^(3+)] is 0.04M then the duration of process is:-

A 500mL sample of a 0.1M Cr^(3+) is electrolyzed with a current of 96.5A . If the remaining [Cr^(3+)] is 0.04M then the duration of process is:-

A 500mL sample of a 0.1M Cr^(3+) is electrolyzed with a current of 96.5A . If the remaining [Cr^(3+)] is 0.04M then the duration of process is:-

A 250 mL sample of 0.20MCr^(3+) is electrolysed with a current of 96.5 A. If the remaining concentration of Cr^(3+) ions is 0.1 M, the duration of electrolysis is (Atomic mass of Cr=52)
