The difference in the water levels of a beaker holding an upside-down buret containing a pocket of hydrogen gas is 23 cm H2O. What is the difference in pressure (pressure correction factor) between the atmospheric pressure and the pressure inside the buret? Express this in torr.

Pressure difference = 16.9 torr

Explanation:

The formula to be used since their is a difference in water level in the beaker and burette is;

Atmospheric pressure = pressure of gas in burette + pressure of water

Atmospheric pressure - gas pressure = pressure of water

Therefore, the difference between atmospheric pressure and gas pressure can be seen to be the pressure of the water

The pressure of water in mmHg = 23 cm H20 = 230 mmH2O

To convert to mmHg, we have to divide by 13.6 since mercury is 13.6 times heavier than water.

Pressure of water = 230 mmH2O * (1 mmHg/13.6 mmH20) = 16.9 mmHg

Since I mmHg = 1 torr, therefore,

Pressure difference = 16.9 torr
