Dalton's Law of Partial Pressure

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

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

In a mixture of gases, each gas exerts pressure independently of the others.

• TRUE

• FALSE

Steam distillation is based on:

• Avogadro's law

• Dalton's law

• Charles' Law

• None of these

Which statement best describes the relationship between gas mixtures and partial pressures according to Dalton's Law?

• The partial pressure of each gas in a mixture is independent of the presence of other gases.

• The partial pressure of a gas decreases as more gases are added to the mixture.

• The partial pressure of a gas is directly proportional to its molecular weight.

• The partial pressure of each gas is determined by the total volume of the gas mixture.

Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of individual gases. If a container holds oxygen at 2 atm and nitrogen at 3 atm, what is the total pressure inside the container?

• 5 atm

• 1 atm

• 6 atm

• 4 atm

How is the partial pressure of a gas in a mixture calculated using Dalton's Law?

• By multiplying the total pressure by the volume fraction of the gas.

• By dividing the volume of the gas by the total volume of the mixture.

• By multiplying the mole fraction of the gas by the total pressure of the mixture.

• By adding

If the partial pressures of hydrogen and oxygen in a container are 300 mmHg and 700 mmHg respectively, what is the total pressure in the container?

• 1000 mmHg

• 400 mmHg

• 300 mmHg

• 700 mmHg

Dalton's Law of Partial Pressures is particularly useful in calculating the pressure of gases in:

• Chemical reactions

• Gas mixtures

• Solids

• Liquids

Which of the following is a direct application of Dalton's Law of partial pressures?

• Predicting the boiling point of a liquid mixture.

• Calculating the pressure inside a balloon filled with helium and oxygen.

• Determining the solubility of a gas in water at a given temperature.

• Measuring the speed of sound in air.
