Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure
= 1.03 atm = 104.325 K pa
Initial temperature
= 26 °c = 299 K
Initial volume
= 22.4 L
Final temperature
= 22 °c = 295 K
Final pressure
= 0.81 atm = 82 K pa
We know that

Put all the values in above formula we get

= 28.11 L
This is the final volume of the balloon.
