Problem 17.39

A 3700 mL flask is initially open in a room containing air at 1.00 atm and 20 ∘C. The flask is then closed and immersed in boiling water. When the air in the flask has reached thermodynamic equilibrium, the flask is opened and air is allowed to escape. The flask is then closed and cooled back to 20 ∘C.

Part A: Find the maximum pressure reached in the flask. Express your answer with the appropriate units.

p_max = ?

Part B: Find the number of moles that escape when air is released. Express your answer with the appropriate units. n = ?
