cb Top Hat 69% Assigned as HQ10.40 A balloon is filled with 0.5 mol of krypton and 0.5 mol of helium at 25 "C. 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 Hint: Consider that real-world plastic balloons are not completely sealed containers O A Larger/more krypton than helium B Smaller/more krypton than helium O C Larger/more helium than krypton O D Smaller/more helium than krypton E Unchanged/equal amounts of krypton and helium Unanswered ALIENWARE

there should be :

more mass of Kr than Helium

then

choose A and D
