A Nitrox II gas mixture for scuba diving contains oxygen gas at 50atm and nitrogen gas at 98atm .
What is the total pressure, in atm, of the scuba gas mixture?
Ptotal = pN2 + pO2
To find the total pressure of the scuba gas mixture, you need to add up the partial pressures of the two gases.
The partial pressure of a gas is the pressure that the gas would exert if it were the only gas present in the container.
In this case, the partial pressure of oxygen gas is given as 50 atm, and the partial pressure of nitrogen gas is given as 98 atm.
To find the total pressure, simply add the partial pressures together:
Total pressure = partial pressure of oxygen + partial pressure of nitrogen
Total pressure = 50 atm + 98 atm
Total pressure = 148 atm
Therefore, the total pressure of the scuba gas mixture is 148 atm.
