How do you use Dalton's law to calculate partial pressure?

Dalton's law of partial pressure states that in a gaseous mixture, the partial pressure exerted by a gaseous component, its partial pressure is the same as if it ALONE occupied the container.


See this answer for the partial pressure of oxygen in our atmosphere. And thus the pressure exerted by a gas in a mixture is proportional to its mole fraction.
