A 3000ml flask is initially open to air at 22degc and 1atm, Ask an Expert

Academics

A 3000mL flask is initially open to air at 22°C and 1atm 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 22°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?
