1. (P1V1 = (P2V2)
Substitute and solve for the one unknown you have which is V2.
Note: I assume that since you don't know the temperature at the bottom of the ocean and you don't list the temperature at top that you don't expect any corrections to be made for the vapor pressure of water.
2. (P1V1) = (P2V2)
Substitute and solve for P2.
Post your work if you get stuck.
Hello, does anyone know how to solve these problems?
1. A bubble of CO₂ with a volume of 0.245 cm³ is released at the bottom of the ocean where the pressure is 388.7 kPa. What will the volume of the bubble be (in cubic centimeters) when it reaches the surface where the pressure is 765 mmHg?
2.A diver with a lung volume of 6.25 L at a pressure of 785 torr dives into the water until her lung volume is 5.87 L. What is the pressure of the water (in atmospheres) pushing on her at this depth?

Thanks for the help!
*I also forgot to note that is says to round to 3 significant figures.
So I did the work with the formula that you wrote, but it says my answer is wrong. I tried rounding the answers in different ways, but it still was wrong. Here is my work:
1. 0.245*388.7=765*x
I got 0.124485, which I rounded to 0.124
2. 6.25*785=x*5.87
I got 835.81771, which I rounded to 836.
Do you know why these answers are incorrect?
