Calculating Properties of Gas Mixture in 4L Flask

[maluce]

Please can someone give me a solution of this problem?

One liter N2 at 2.1 bar and two liters of Ar at 3.4 bar are mixed in a 4L 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 respectively 304 K and 402 K and the final one is 377 K.

Thank you!

You need to show your attempt before we can help you. If you need help getting started, you will need to use the fact that the total pressure is just the sum of the partial pressures
