Two flasks are connected with a stopcock. The first flask has a volume of 5 liters and contains nitrogen gas at a pressure of 0.75 atm. The second flask has a volume of 8 liters and contains oxygen gas at a pressure of 1.25 atm. When the stopcock between the flask is opened and the gases are free to mix, what will the pressure be in the resulting mixture?
