Chemistry - Stoichiometry Question with Solution | TestHub

One of the major uses of H₂O₂ is for artificial respiration. It is stored in a cylinder of 3 L capacity, completely filled with H₂O₂ solution with a volume strength of 44.8 volumes at 1 atm and 273 K. In a hospital in Ahmedabad, a patient under artificial respiration takes 200 mL O₂ per minute at 1 atm and 273 K, and a cylinder lasts for 2.8 hours. After that, it cannot be used for respiration, even though it still contains H₂O₂. [Assume the volume of the solution and the rate of decomposition remain constant.]
