Answer:

Partial pressure of Ar = 4.7 atm

Explanation:

Total pressure of a mixture of gases = Sum of partial pressure of each gas

This mixture contains: O₂, He and Ar.

Total pressure = 15.3 atm

Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar

15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar

Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm

Partial pressure of Ar = 4.7 atm
