Looking to find out the amount of vacuum needed in inches Hg to remove partial pressure of a gas in a tank.

Is there a way to do so? I don't know how to relate the size of vacuum to the partial pressure of the gas.
And I am not sure how to find the partial pressure of Oxygen in a tank if the tank is half full of water (which itself has gasses in it) and half full of the gas
