A 2900-mL flask is initially open to air at 23 ∘C and 1 atm pressure. It's then closed and immersed in boiling water. When it has reached equilibrium, the flask is opened and air is allowed to escape. Then it's closed and cooled back to 23 ∘C. a. What's the maximum pressure reached in the flask? b.

When it has reached equilibrium, the flask is opened and air is allowed to escape. Then it's closed and cooled back to 23 ∘C.
a. What's the maximum pressure reached in the flask?
b. How many moles escape when the air is released?
c. What's the final pressure?
