# 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.
