Avogadro's Law, Dalton's Law, Ideal Gas Law

A container holds three gases: oxygen, carbon dioxide, and helium. The partial pressures of the three gases are 2.00 atm, 3.00 atm, and 4.00 atm, respectively. What is the total pressure inside the container?

• 2 atm
• 4 atm
• 3 atm
• 9 atm

80.0 liters of oxygen is collected over water at 50.0 °C. The atmospheric pressure in the room is 96.00 kPa. What is the partial pressure of the oxygen?

• 96.00 kPa
• 83.66 kPa
• 108.34 kPa
• 12.344 kPa

• 752 mm Hg
• 159 mm Hg
• 593 mm Hg
• 434 mm Hg

• 760 torr
• 736.2 torr
• 796.2 torr
• 1 atm

Equal volumes of different gases at the same temperature and pressure have the same number of moles.

• True
• False

• 550 kPa
• 900 kPa
• 200 kPa
• 350 kPa

• Helium
• Nitrogen 
• Oxygen
• All have the same number of molecules
