Answer: The volume of the balloon up there is 6.192 L.
Explanation:
Given: 
= 1.80 L, 
= 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm
= 0.300 atm, 
= ?
Formula used to calculate volume is as follows.
Substitute the value into above formula as follows.
Thus, we can conclude that the volume of the balloon up there is 6.192 L.
It really depends on the 'type' of rock it is. By this I mean whether it's impermeable or permeable. Impermeable rocks don't allow water through and permeable rocks do. It has to do with how 'porous' a rock is: how many openings it has and how spaced apart are its particles are. Sandstone is permeable and Shale impermeable.
