Question

A tank contains a mixture of helium, neon, and argon gases. lf the total pressure in the tank is 490. mmHg and the partial pressures of helium and argon are 21.5 mmHg and 10.2 mmHg, respectively, what is the partial pressure of neon?

Answer 1

Answer:

458.3 mm Hg

Explanation:

This question is based on the principle of dalton law.

it says that the total pressure of a mixture of gas is the sum of partial pressures of individual gases.

We are given total pressure= 490 mmHg

Partial pressure of Helium = 21.5 mm Hg

Partial Pressure of Argon = 10.2 mm Hg

Partial pressure of Neon will be total pressure -( sum of partial pressure of He and Ar)

which is 458.6 mm Hg
