Question

Three gases, nitrogen, helium, and krypton are confined in a 9.00 Lvessel at a pressure of 7.00 atm. The vessel contains 5.00 moles ofnitrogen, 2.00 moles of helium, and 2.00 moles of krypton. What isthe partial pressure of helium?

1. Partial pressure of helium = ? atm

Now suppose that 8.00 moles of neon are added to the vessel withoutchanging the volume or temperature. What is the partial pressure ofhelium now?

2. Partial pressure of helium after addition of neon = ? atm

Now suppose that an additional 5.00 moles of helium are added tothe vessel, again without any change in the volume or thetemperature. What is the partial pressure of helium now?


3. Partial pressure of helium after addition of 5.00 more moles ofhelium = ? atm
