The partial pressure of nitrogen in air is 592 torr. Air pressure is 752 torr, what is the mole fraction of nitrogen?

The mol fraction of nitrogen is 0.787

Explanation:

Step 1: Data given

Partial pressure of nitrogen = 592 torr

Air pressure = 752 torr

Step 2: Calculate mol fraction

P1/PT = n1/nT = mol fraction

⇒ P1 = the partial pressure of nitrogen = 592 torr

⇒ PT = The total pressure = air pressure = 752 torr

⇒ n1 = number of mol of nitrogen

⇒ nT = Total number of mol

Mol fraction of nitrogen in air = 592/752 = 0.787

The mol fraction of nitrogen is 0.787
