Water in the Manometer.

The system shown in the diagram is at equilibrium at $300K$ and the volume of the bulb is $150 ml$ which contains Oxygen gas and some amount of liquid water. If the bulb contains $0.001$ $mol$ of ${ 0 }_{ 2 }(g)$ , then the volume of liquid water is approximately _ _ _ _ __ $ml$ .

$Details$ $and$ $Assumptions$

At $300K$ Vapour pressure of water is $28 mm$ $of$ $Hg$ .

$h=161 mm$ .

The manometer is closed and the space above the other end is a Vacuum.
