Gas Laws

Vapor pressure and temperature

The vapor pressure of water at 22 degrees C is 19.800 torr. If you put 26.662 g of water in a cubic container that is 1.1000 m on an edge, will there be any liquid water remaining in the container at 22 degrees C or will it all be vapor? R = 0.0820578 L*atm/K*mol.

Ideal Gas Law - Temperature of Boiling Point of Chlorine

A hydrogen gas thermometer is found to have a volume of 100.0 cm3 when placed in an ice-water bath at 0°C. When the same thermometer is immersed in boiling liquid chlorine, the volume of hydrogen at the same pressure is found to be 87.2 cm3. What is the temperature of the boiling point of chlorine?

Calculating the Volume of Gas on Venus

The surface temperature of Venus is about 1050K and the pressure is about 75 Earth atmospheres. Assuming that these conditions represent a Venerian "STP", what is the standard molar volume (in liters) of a gas on Venus?

Gas equations

Ozone molecules in the stratosphere absorb much of the harmful radiation from the sun. the temp. and the pressure of ozone in the stratosphere are 250 K and 1.0*10^-3 atm. How many ozone molecules are present in 1.0 L of air under these conditions?

Change in gas pressure when volume is decrased

A volume of gas is decreased by half while the temperature remains constant. How much does the gas pressure change? (2) State the relationship between the volume and pressure of a gas when the temperature is held constant (Boyles law). (3) Does data taken in an experiment support the idea that the pressure times the volume

Will Pressure Exceed Capacity?

Question: A metal tank of volume 75.5 L will burst if the pressure in it exceeds 50.0 atm. Will this pressure be exceeded by 82.0 moles of a gas in it at 25 degrees Celsius?

The Ideal Gas Law to Determine the Molecular Weights of Gas

At a given temperature a certain number of grams of CH4, when placed in a 10 L vessel, exerts a pressure of 0.240 atm. An equal number of grams of gas B, when placed in a 12 L container at the same temperature, exerts a pressure of 0.145 atm. Calculate the approximate molecular weight of gas B.
