Ideal Gas Law and Partial Pressure

At 17°C, a 0.80 mole sample of a gas exerts a pressure of 1.2 atm. What is the volume of the container?

• 23 L

• 2400 L

• 0.063 L

• 16 L

Dalton's Law states that

• At a constant temperature, the volume of a confined ideal gas varies inversely with its pressure

• The total pressure of a mixture of gases is equal to the sum of the partial pressures of each gas

• Gases tend to expand when heated

• The density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas

• 7.97 atm

• 11.0 atm

• 23.2 atm

• 1.45 atm

30% of a gaseous mixture is nitrogen and 70% is helium. The total pressure in the container is 4 atm. What is the partial pressure of the nitrogen?
