An empty oven with a volume of 0.106 m3 and a temperature of 292 Kelvin is turned on. The oven is vented therefore that the air pressure inside it is always the equal as that of the atmosphere. Initially, the air pressure is 1.00x105 Pascal, but after the oven has warmed up to a final temperature of 419 Kelvin, the atmospheric air pressure has decreased to 9.86x104 Pascal due to a change in weather conditions. Find how many moles of air leave the oven while it is heating up?
