A tank contains #N_2# at 1.0 atm and #O_2# at 2.0 atm. Helium is added to this tank until the total pressure is 6.0 atm. What is the partial pressure of the helium?
In a gaseous mixture, the partial pressure exerted by a gas is the same if that gas alone had occupied the container. The total pressure is the sum of the partial pressure.
We know that the total pressure is
Since we have been given the other partial pressures, calculation of
