`H_(2)O_(2)` solution of 45.4 V at STP . In a hospital of Kota, patient under artifical respiration take s200ml `O_(2)` per min at 1 atm and 273 K and a cylinder last for 2.8 hours . After that it cannot be used for respiration though it still contains `H_(2)O_(2)` .
[Assume volume of solution and rate of decomposition remain constant]
Volume strenght of `H_(2)O_(2)` left in solution is:
A. 11.35 V
B. 22.7 V
C. 5.67 V
D. 34.05 V
