• 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?
