Dalton's Law of Partial Pressure

A container holds three gases: oxygen, carbon dioxide, and helium. The partial pressures of the three gases are 2.00 atm, 3.00 atm, and 4.00 atm, respectively. What is the total pressure inside the container?

• 2 atm
• 4 atm
• 3 atm
• 9 atm

A mixture of hydrogen, nitrogen, and water vapor has a total pressure of 864 mmHg. The partial pressure of hydrogen is 220 mmHg and that of nitrogen is 410 mmHg. What is the partial pressure of water vapor?

• 234 mmHg
• 1.37 mmHg
• 2.64 mmHg
• 1, 494 mmHg

The partial pressure of gas X is 340 torr. The partial pressure of gas Y is 264 torr. The partial pressure of gas Z is 100 torr. What is the total pressure exerted by the gases in this system? 

• 76 torr
• 440 torr
• 604 torr
• 704 torr

A container is filled with H₂, and H₂O. Calculate the partial pressure of H₂ when the pressure of water is 17 torr. The total pressure of the gases is 750 torr.

• 767.5torr
• 733torr
• 42.86torr

Dalton's Law states...

• that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.
• that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases
• how gases tend to expand when heated
• that the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.
