An empty oven with a volume of 0.150 m3 and a temperature of 296 K is turned on. The oven is vented so that the air pressure inside it is always the same as the air pressure of the environment. Initially, the air pressure is 1.00 × 105 Pa, but after the oven has warmed up to a final temperature of 453 K, the atmospheric air pressure has decreased to 9.50 × 104 Pa due to a change in weather conditions. Determine how many moles of air leave the oven while it is heating up.
