An airplane is pressurized with air to 660 mmHg . If air is 21% oxygen, what is the partial pressure of oxygen on the plane?

The partial pressure of oxygen on the plane is 138.6 mmHg

Explanation:

To calculate the partial pressure of the gas, we use the equation given by Raoult's law, which is:

where,

= partial pressure of oxygen gas = ?

= total pressure = 660 mmHg

= mole fraction of oxygen gas = 21 % = 0.21

Putting values in above equation, we get:

Hence, the partial pressure of oxygen on the plane is 138.6 mmHg

h let me think

the ratio of the conjugate base to the acid required to attain the desired ph.
