Question

A nitrox ii gas mixture for scuba diving contains oxygen gas at 53 atm and nitrogen gas at 94 atm . what is the total pressure, in torrs, of the scuba gas mixture?

Answer 1

Answer: The total pressure will be 1,11,720 torr.

Explanation:

Partial pressure of nitrogen gas.$p_{N_2}=53 atm=53\times 760 torr= 40,280 torr$ (1atm = 760 torr)

Partial pressure of oxygen gas,$p_{O_2}=94 atm=94\times 760 torr=71,440 torr$

Total pressure, in torrs, of the scuba gas mixture = 40280 + 71440 torr =111,720 torr

Hence , the total pressure in scuba gas mixture is 111,720 torr.
