A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa. If Po2 =

HACTEHA [7]

Answer:

A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.

The pressure for oxygen is 3 kPa

Explanation:

According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.

$P_{total}=P_{1}+P_{2}+P_{3}$

So,

For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:

$P_{total}=P_{O_{2}}+P_{N_{2}}+P_{CO_{2}}$

$P_{total} = 32.5kPa$

$P_{O_{2}} = 6.5kPa$

$P_{N_{2}} = 23.0kPa$

Insert the values in :

$P_{total}=P_{O_{2}}+P_{N_{2}}+P_{CO_{2}}$

$32.5 kPa = 6.5 kPa + 23.0 kPa +P_{CO_{2}}$

$32.5 kPa = 29.5 kPa +P_{CO_{2}}$

$P_{CO_{2}}= 32.5 - 29.5$

$P_{CO_{2}}= 3kPa$
