Answer:
The final volume of the bubble is 7.13 mL.
Step-by-step explanation:
The combined gas equation is,
where,
= initial pressure of gas = 3 atm
= final pressure of gas = 0.95 atm
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:

The final volume of the bubble is 7.13 mL.
