In a mixture of He, O, and N, gases He exerts a partial pressure of 15.22 mm Hg and
gayaneshka [121]

Answer:

P(N)  = 38.48 mmHg

Explanation:

Given data:

Partial pressure of He = 15.22 mmHg

Partial pressure of O = 35.21 mmHg

Partial pressure of N = ?

Total pressure = 88.91 mmHg

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Now we will solve this  problem by using this law.

P(total) = P(He) + P(O) + P(N)

88.91 mmHg = 15.22 mmHg + 35.21 mmHg + P(N)

88.91 mmHg = 50.43 mmHg + P(N)

P(N)  = 88.91 mmHg  - 50.43 mmHg

P(N)  = 38.48 mmHg
