atmospheric pressure is 25.65 inches of mercury. Convert inches of mercury to Torr. ( there are 2.54cm to the inch )
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
Question 1 (1 point) The atmospheric pressure was measured to be 29.97 inches of mercury (inHg). Given the fact that 1 atm = 29.92 inHg, convert the measured atmospheric pressure into atm. Use four significant figures in your answer. Your Answer: Answer units
The following data was obtained: atmospheric pressure: 752 torr water vapor pressure: 22 torr height of water column: 158 mm Calculate the partial pressure of the dry gas. Density of mercury if 13.6 g/cm3 and assume the desnity of the solution is 1.00 g/cm3/
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,...
Suppose atmospheric pressure is 29.74 inches. Convert this to atm. When the ideal gas law iconstant 0.0821 atm L/ K mol is used, the pressure must be in atm.
Part A The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg). According to this barometer, what is the atmospheric pressure P in inches of mercury (inHg)? Express your answer in inches of mercury using five significant figures. P = inHg SubmitHintsMy AnswersGive UpReview Part Part B At a pressure of 897 mbar , what would the height of the mercury in the column of a mercury barometer?

2. A barometer reads the atmospheric pressure 764.7 torr. A sample of gas is placed attached to an open-end mercury monometer. The level of mercury in the op arm of the monometer has a height of 136.4 mm, and that in the arm that is in cont with the gas has a height 103.8 mm. What is the pressure of gas in atmosphere?
At 250C the vapor pressure of mercury is 74.4 torr and at 320C
the vapor pressure is 376.3 torr. Find the
Hvap in KJ/mol.
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

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 ,...
