A liquid that has an equilibrium vapor pressure of 129 torr at 25°C is placed into a 1-L vessel like that shown below.
A few mL of the liquid is introduced into the vessel at 25°C while it has a pressure of 1.00 atm of air in it, without allowing any of the air to escape. After a few minutes a few drops of liquid remain in the vessel. What is the pressure difference shown on the manometer?
how do i start this?

I can't see the diagram and you can't draw it on this forum. If the diagram is what I think it is the pressure difference will be 129 torr.
The new pressure in the closed vessel is 760 mm + 129 mm. It was 760.

760 torr is wrong

760 is not what I said. Reread my answer.
