An empty oven with a volume of 0.125 m3 and a temperature of 293 K is turned on. The oven is vented so that the air pressure inside it is always the same as that of the environment. Initially, the air pressure is 1.00x105 Pa, but after the oven has warmed up to a final temperature of 418 K, the atmospheric air pressure has decreased to 9.44x104 Pa due to a change in weather conditions. How many moles of air leave the oven while it is heating up?
