Question

Two flasks (which we will refer to as flask 1 and flask 2) are connected to each other by a U-shaped tube filled with an oil having a density of 0.775 g mL-1.

The oil level in the arm connected to flask 2 is 12.66 cm higher than in the arm connected to flask 1. Flask 1 is also connected to an open-end mercury manometer.

The mercury level in the arm open to the atmosphere is 16.03 cm higher than the level in the arm connected to flask 1. The atmospheric pressure is 0.789 atm.
What is the pressure of the gas in flask 2 expressed in torr?

Pressure =___torr
