PRACTICE: Dalton's Law of Partial Pressure

Steam distillation is based on:

• Avogadro's law

• Dalton's law

• Charles' Law

• None of these

Two gases A and B with a mole ratio of 3:5 respectively, are combined in a container and exert a pressure of 8 atm. If B is removed, what would be the pressure due to A only, with the temperature remaining constant?

• 5 atm

• 2 atm

• 3 atm

• 4 atm

A container holds four times as many moles of CO₂ as O₂. If the total pressure in the container is 20 atm, what is the pressure exerted by carbon dioxide?

On Venus, the atmospheric pressure is 2700 mmHg and nitrogen gas makes up 3.0% of the atmosphere. What is the partial pressure of nitrogen on Venus?

• 2697 mmHg

• 81 mmHg

• 2619 mmHg

• 3 mmHg

A flask holds five times as many moles of N₂ as O₂. If the total pressure in the jar is 18 atm, what is the pressure exerted by oxygen?

• 18 atm

• 6 atm

• 3 atm

• 15 atm

Given that a vessel contains 0.672 mol O₂, 0.128 mol CO₂, and 0.200 mol N₂. If the total pressure of the vessel is 100 atm, what are the partial pressure of O₂, CO₂, and N₂ respectively. _{(That means, in that order).}

• 67.2 atm, 12.8 atm, 20.0 atm

• 67.2 atm, 20.0 atm, 12.8 atm

• 20.0 atm, 67.2 atm, 12.8 atm

• 12.8 atm, 20.0 atm, 67.2 atm

The pressure of a mixture of nitrogen, carbon dioxide, and oxygen is 300 kPa.
What is the partial pressure of oxygen is the partial pressures of the nitrogen and carbon dioxide are 200 kPa and 48 kPa, respectively. _{(That means, in that order)}

• 52 kPa

• 218 kPa

• 26 kPa

• 148 kPa

If two gases, A and B, in separate 1 liter containers exert pressures of 2 atm and 3 atm respectively, what will be the pressure exerted when both gases are put together in a single 1 liter container?

• 5 atm

• 6 atm

• 10 atm

• 11 atm

• 0.2 atm

• 0.3 atm

• 0.4 atm

• 0.5 atm

Complete the sentence using total, partial, or complete. The pressure that one particular gas exerts when it is part of a mixture of gases is called the pressure of that gas.
