One liter of N2(g) at 2.00 bar and two liters of Ar(g) at 3.60 bar are mixed in a 3.45-L flask to form an ideal-gas mixture. Calculate the value of the final pressure of the mixture if the initial and final temperature of the gases are the same. Repeat this calculation if the initial temperatures of the N2(g) and Ar(g) are 309 K and 406 K, respectively, and the final temperature of the mixture is 373 K. (Assume ideal-gas behavior.)
