5-25 A gas in a bulb as in Figure 5-3 registers a pressure of 833 mm Hg in the manometer in which the reference arm of the U-shaped tube (A) is sealed and evacuated. What will the difference in the mercury levels be if the reference arm of the U-shaped tube is open to atmospheric pressure (760 mm Hg)?
Target check For each of the macroscopic charcateristics unique to the gas phase of matter described in section 4.1-a compressibility, b expandability, c low density, d may be mixed in a fixed volume, and e uniform, constant pressure on container walls-describe how a postulate of the kinetic molecular theory explains the reason for the characteristic.
The gas in the discharge cell of a laser contains (in mole percent) 11% CO2, 5.3% N2, and 84% He. (a) What is the molar mass of this mixture? (b) Calculate the density of this gas mixture at 32C and 758 mm Hg. (c) What is the ratio of the density of this gas to that of air (MM=29.0g/mol)at the same conditions?
At 27 °C, 500 cc of H2, measured under a pressure 400 torr, and 1000 cc of N2, measured under a pressure of 600 mm Hg, are introduced into an evacuated 2-L flask. Calculate the resulting pressure. (Given -> Unknown -> Solution -> Answer)
1.) A gas at 250 K and 1520 kPa has a molar volume 12% smaller than that calculated from theperfect gas law. Calculate (a) the compression factor under these conditions, and (b) the molarvolume of the gas. Answer: [0.88; 1.20] 2.) At 300 K and 2026 kPa, the compressibility factor of a gas is 0.86. Calculate the volume occupied by 8.2 mmol of the gas under these conditions. Answer: [8.68 x 10^-3]
1. The compressibility factor Z = PV/nRT for O2 at -27.1°C and 537.1 atm is 1.50; at 147.4°C and 95.5 atm, it is 1.02. A certain mass of oxygen occupied a volume of 3.28 L at 147.4°C and 95.5 atm. Calculate the volume occupied by the same quantity of oxygen at -27.1°C and 537.1 atm. 2. The composition of a mixture of gases in percentage by volume is 20.5% nitrogen, 15.7% carbon monoxide, 37.8% water, and the rest sulfur dioxide. Calculate the density of the gaseous mixture at 39.8°C and 1.46 atm in grams/liter. Report your answer to the hundredths position.
Dry ice is sometimes used for special effects to form a "fog" as it sublimes from the solid to the gaseous state. If 99.0 grams of dry ice is used to generate this "fog", how many torr of pressure will be exerted by the gaseous carbon dioxide once all of the dry ice sublimes? Assume the volume of the auditorium where the fog is generated is 1.24 x 10^{5}5 m^{3 }3and the temperature is 22ºC. (Enter your answer using either standard or scientific notation. For scientific notation, 6.02 x 10^{23}23 is written as 6.02E23.)
The volume of a balloon (V) and the pressure on that balloon (P) are related by the equation: PV=4500 (Boyle's Law). At a particular moment in time, the pressure on the balloon is 20 psi (pounds per square inch) and is increasing at the rate of 2.4 psi/hour. At what rate is the volume (measured in in^3) changing at that time? Label your answer with the appropriate units)

Ethanol vapours were allowed to completely fill a jug with a volume of 18.9L. The ethanol was burned yielding 9.6mL of LIQUID water in the bottom of the jug. C2H5OH + 3 O2 ---> 2 CO2 + 3H20 If the room temperatue was 23.5 degrees Celsius and the pressure was 97.5 KpA, calculate the percentage yield of the water gathered in the jug. Select the final answer from the options below: - Not enough information - 76% - 24% - 17%
Consider Figure 13.1. If the height of the mercury column in the leveling bulb is 21 mm greater than that in the gas buret and atmospheric pressure is 600 mm , what is the pressure on the gas trapped in the buret? Should I assume (1 atm) or would I assume the atm is 600mm (standard) and subtract the 21 from the 600, then convert by division (600-21)/760 ?? thanks
What is the pressure of a gas (in units of torr) in an open-end mercury-based (Hg density = 13,593 kg/m3) Manometer at sea level (Patompshere = 101,396 Pa) if the hydrostatic pressure head reads such that the level of the mercury exposed to the interior gas in the bulb is 51.5 mm above that of the mercury exposed to the atmosphere?
