An equimolar mixture of n2(g) n 2 ( g ) and ar(g) ar ( g ) is kept inside a rigid container at a constant temperature of 300 k k. The initial partial pressure of ar ar in the mixture is 0. 75atm 0. 75 atm. An additional amount of ar ar was added to the container, enough to double the number of moles of ar ar gas in the mixture. Assuming ideal behavior, what is the final pressure of the gas mixture after the addition of the ar ar gas?.
