A vessel contains a mixture of nitrogen and oxygen. If the partial pressure of nitrogen is 20 atmospheres and the partial pressure of oxygen is 42.8 atmospheres, what is the total pressure inside the vessel?

Datlon's law of Partial Pressures states that in a gaseous mixture, the partial pressure exerted by a gaseous component is the same as the pressure it would exert if it ALONE occupied the container. The total pressure is the SUM of the partial pressures.

For your problem #P_"Total"=P_"dinitrogen"+P_"dioxygen"# #=# #(20+42.8)*atm#.
