This is the situation at the start of your experiment. The entire system is at vacuum, and the mercury is at the
bottom part of the Toepler pump.

The valve at the right-hand side is directed to the pump to retain the mercury at the bottom part.

After opening the reaction vessel, the gas formed in the reaction will enter the top part of the Toepler pump.

By directing the valve to atmospheric pressure, the mercury will be pushed upwards, thus compressing the
gas that was in the upper part.

At a certain point, the compressed gas will be pushed through the mercury lock.

By directing the valve back to the pump again, the mercury will be transferred back to the bottom .

When the mercury is transferred back to the bottom part, the remaining gas will equilibrate.

At a certain point, all the gas is transferred into the calibrated volume. Now you can push the mercury
upwards...

You can measure the pressure in the calibrated volume, by reading the difference in height in the two
legs, and calculate the amount of gas.
