**Hello.**

I've been struggling to solve the following problem. We have to calculate the depth (in m) to which a balloon full of Kr must be pushed underwater to make it sink to the bottom of the sea. It takes place at 25 degrees Celsius, we know that p (atm) = 101 325 Pa, density (of sea H_{2}O) = 1.04 g/cm^{3}, g = 9.81 m/s^{2} and the M (Kr) = 83,8 g/mol, and that Kr acts as an ideal gas.

Firstly, I've calculated the density of Kr ( = 3.74 g/dm3), and I know that the p (fluid) = ρ * h * g. Does anyone have any ideas about what to do next?

**Thank you!**
