Two flasks are connected with a stopcock, a valve used to restrict or isolate the flow of a liquid or gas through a pipe. The first flask has a volume of 6.45 liters and contains helium gas at a pressure of 0.84 atm. The second flask has a volume of 7.75 L and contains oxygen gas at a pressure 1.75 atm. When the stopcock between the flasks is opened and the gases are free to mix, what will the pressure be in kilopascals in the resulting mixture
