PLEASE HELP: Two flasks at the same temperature are joined by a glass tube with a valve. Flask A is a 1.35L flask containing N, (g) at 1.58 atm, while flask B is a 0.55 L flask containing CO(g) at 1.20 atm. What is the final pressure in the flasks after the valve is opened? I got 1.47 but my teacher got 1.00.
