Dalton's 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

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

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

In a mixture of gases, the total pressure is 760 mmHg. If the partial pressure of oxygen is 200 mmHg and nitrogen is 500 mmHg, what is the partial pressure of the remaining gas?

• 60 mmHg

• 100 mmHg

• 160 mmHg

• 260 mmHg

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.

What is the definition of partial pressure in a gas mixture?

• The pressure that each gas would exert if it occupied the entire volume alone at the same temperature.

• The total pressure exerted by the sum of all gases in a mixture.

• The pressure exerted by the gas molecules when they collide with the walls of a container.

• The decrease in pressure when a gas is mixed with another gas.

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

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?
