A sample of oxygen is collected over water and has a volume of 2.23 mL. The pressure of the collected 'wet' gas is 61.78 kPa and the temperature is 20°C. What will the volume of the 'dry' oxygen be in mL if the pressure is changed to 94.91 kPa, assuming the temperature remains constant?

Under which conditions of pressure and temperature does a real gas behave most like an ideal gas?

Which of the following gases would be expected to deviate most from ideal behavior under standard conditions?

Using the Ideal Gas Law, calculate the final temperature when 2.00 L of an ideal gas at 20.0°C is compressed to 1.00 L, assuming constant pressure.

When you heat a sample of gas at constant volume, which of the following will occur according to the ideal gas law?

Under which conditions does a real gas behave most like an ideal gas?

If the pressure, temperature, and amount of gas are kept constant, would the volume of the gas be different if the gas was argon instead of another ideal gas?

A sample of gas occupies 1000 mL at a pressure of 15 atm. If the gas is compressed to a volume of 500 mL at constant temperature, what is the new pressure of the gas?

39.9 liters of hydrogen are collected over water at 76.0°C and have a pressure of 439 torr. What would the pressure (in torr) of the 'dry' hydrogen at 29.4°C in an 18.5 liter container be? (Water Vapor Pressure at 76.0°C is 301.4 torr)

A balloon initially has a pressure of 2.9 atm, a volume of 4.5 L, and a temperature of 349.3 K. If the pressure changes to 3.4 atm and the volume to 6.5 L, what is the new temperature of the balloon?

A 25.0 L sample of oxygen gas (O_2) is collected at 5.20 atm and 28.0 °C. Using the ideal gas law, how many grams of O_2 are present in the sample?

Which of the following is an example of an accurate manipulation of the ideal gas law?

How does the pressure of a real gas compare to the pressure of an ideal gas at low temperatures?

A 75.0 g sample of dinitrogen monoxide (N2O) is confined in a 4.12 L vessel. What is the pressure (in atm) at 205°F, assuming ideal gas behavior?
