Question

What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mmHg and the partial pressure of helium is 439 mmHg?

Answer 1

The partial pressure of hydrogen gas in a mixture of hydrogen and helium is :

-161mmHg

"Dalton Law of partial pressure"

Given :

• Total pressure = 600 mmHg
• Partial pressure of helium=439 mmHg
• Partial pressure of hydrogen=?

As per Dalton's Law of partial pressure , Total pressure is equal to the summation of individual partial pressure.

Formula :

$P_{Total} = P_{Helium} +P_{Hydrogen}$

600 mmHg= 439 mmHG+$P_{hydrogen}$

$P_{Hydrogen}$=161 mmHg

The partial pressure of hydrogen gas in a mixture of hydrogen and helium is 161mmHg.
