A balloon is filled with 05 mol of krypton and 05 mol of hel

A balloon is filled with 0.5 mol of krypton and 0.5 mol of helium at 25 ºC. The balloon is then left at constant temperature and pressure for 24 hours in a sealed room. After the 24 hours is over the balloon\'s volume will be ________ and the balloon will contain _____.

Solution

initially 0.5 moles Kr and 0.5 moles He present

total moles = 0.5 + 0.5 = 1.0

1.0 mole at 25⁰C = 22.4 L

as T and P constant no change in volume

both are inert gases so there will be no chemical change.

after 24 hr

volume = 22.4 L

balloon contain He and Kr only.
