What is a manometer? How does it measure the pressure of a sample of gas?

A sealed-tube manometer (as shown below) can be used to measure pressures below atmospheric pressure. The tube above the mercury is evacuated. When there is a vacuum in the flask, the mercury levels in both arms of the U-tube are equal. If a gaseous sample is introduced into the flask, the mercury levels are different. The difference h is a measure of the pressure of the gas inside the flask. If h is equal to 6.5 cm, calculate the pressure in the flask in torr, pascals, and atmospheres.If the sealed-tube manometer above had a height difference of 20.0 inches between the mercury levels, what is the pressure in the flask in torr and atmospheres?
