Underwater Pressure: 9.42 ATM, Find Vessel's Depth

[cchiapuzio]

Homework Statement

The pressure exerted on an underwater vessel is 9.42 ATM. If the vessel is in fresh water, to what depth has the vessel descended?

2. Formula

P=Po + pgh

It is fresh water so p=1000 kg/m^3

Hi cchiapuzio and welcome to the forum!
Do you know any formula that relates pressure vs depth? If yes, post it here and try to use it.
Also, what is water density?
