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.
