• 2697 mmHg

• 81 mmHg

• 2619 mmHg

• 3 mmHg

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
