The pressure unit torr is defined as the pressure that will
support a column of mercury 1 mm high. Meteorologists often give
barometric pressure in inches of mercury, defined analogously. The
density of mercury is
.
Part A
Express torr in SI units.
1 torr = Pa
Part B
Express inch of mercury in SI units.
1 inch of mercury = kPa

1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...

The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar
1 Pa = 10-5 bar

EXPERIMENT 12 Name MEASUREMENT OF THE GAS CONSTANT PRE-LAB EXERCISES Central to the study of gases is the idea of pressure. Historically pressure was determined as the ability the raise a column of mercury (Hg) to a particular height. Today, pressures are still often (erroneously) quoted just as a simple distance measurement, such as 75 cm. What is really meant is a column of Hg 75 cm high, so it is not too bad to say P - 75 cm...

a) Convert 0.500 atm of pressure to its equivalent in millimetres of mercury. Express the pressure numerically in millimetres of mercury. b) High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 3.69×108 Pa ,...

Part B Review Constants Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average...

(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury? The density of water is 1.0 g/mL whereas that of mercury is 13.6 g/mL (b) What is the pressure, in atmospheres, on the body of a diver if he or she is 39 ft below the surface of the water when atmospheric pressure at the surface is 0.97 atm?
