Dalton's Law of Partial Pressure

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.

Argon makes up 0.93% of the atmosphere. In a given sample of air, the partial pressure of argon is 6.54 mmHg. What is the pressure of the sample?

• 703 mmHg

• 70.3 mmHg

• 654 mmHg

• 760 mmHg

• TRUE

• FALSE

Increasing the pressure in the cylinder by adding a gas not involved in the reaction will increase the total gas pressure in the cylinder.

• TRUE

• FALSE

What units will be found in the variables of a Dalton's law problem?

• kilopascals (kPa)

• liters (L)

• Kelvins (K)

• moles (mol)

Dalton's law equation is used to find what?

• the density of a pure gas

• the total pressure of a pure gas

• the total pressure of a gas mixture

• the volume of a gas mixture

What is the total pressure of the heliox gas in the diagram?

• 300 kPa

• 100 kPa
