The pressure in the flask of manometer should be determined in units of torr and atm when the manometer shows a reading of 20.0 inches. Concept Introduction: The manometer is a devise used measure the pressure of a gas . The pressure of gas is determined by the value of ‘ h ’ shown by the manometer. This ‘h’-value is added or subtracted with atmospheric pressure to determine the pressure of gas. If the flask side mercury level is decreased after the filling of gas, then the ‘h’-value will be added to atmospheric pressure to get the pressure of gas. Atmospheric pressure = 760 mm Hg /torr The pressure equivalent of ‘h’ value is, h = 1 inch = 25 .4 mm Hg Pressure of a substance can be stated in various units. The units of pressure are interconvertible. The relations between the units of pressure are, Since the unit mm Hg and the unit torr is used interchangeably. 1 mm Hg = 1 torr Conversion of 1 torr into atm is, 1 mm Hg = 1 760 atm

Solution Summary: The author explains that the pressure in the flask of manometer should be determined in units of torr and atm.
The pressure in the flask of manometer should be determined in units of torr and atm when the manometer shows a reading of 20.0 inches.
Concept Introduction:
The manometer is a devise used measure the pressure of a gas. The pressure of gas is determined by the value of ‘h’ shown by the manometer. This ‘h’-value is added or subtracted with atmospheric pressure to determine the pressure of gas.
If the flask side mercury level is decreased after the filling of gas, then the ‘h’-value will be added to atmospheric pressure to get the pressure of gas.
Atmospheric pressure = 760 mm Hg /torr
The pressure equivalent of ‘h’ value is,
h=1inch=25.4mmHg
Pressure of a substance can be stated in various units. The units of pressure are interconvertible. The relations between the units of pressure are,
Since the unit mm Hg and the unit torr is used interchangeably.
