4.1-8 Dalton's Law of Partial Pressures Quiz

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.

The collection flask contains only two gases, CO₂ and water vapor. If the total pressure in the flask is 1.0atm and the vapor pressure of the water is 0.12atm--what is the pressure of the CO₂ in the collection flask?

• 1.0atm

• 0.12atm

• 0.88atm

• 1.12atm

Container T is made combining all the gases from containers A, B, and C. What is the pressure in container C?

• 200kPa

• 550kPa

• 250kPa

• 150kPa

A gaseous mixture contains 5.0 moles of nitrogen and 10.0 moles of helium. The total pressure in the container is 3.0 atmospheres. What is the partial pressure of the nitrogen?

• 1 atm

• 0.5 atm

• 3.0 atm

• 2.0 atm
