Answer: The volume in the balloon at the higher altitude is 260 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 760 torr
= final pressure of gas = 511 torr
= initial volume of gas = 233 L
= 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 volume in the balloon at the higher altitude is 260 L
% yield = actual yield/ theoretical yield x 100%
4.8946 / 0.4 = 12.2365
% yield = 12.2365 x 100 = 1223.65%
