A gas is filled into a bulb connected to an open limb manometer. The level of mercury in the open arm is 2.1 cm lower than that in the other arm of the manometer. The atmospheric pressure is 740 mm. What is the pressure of the gas?

Text Solution

As level in the open arm of the manometer is lower that that in the arm connected to the gas bulb, this means that atmospheric pressure is greater than pressure of the gas by difference of the two levels. Hence, pressure of gas=740-21=719 mm.
