Answer:
P(Xe) = 1.15 atm
Explanation:
Given data:
Total pressure = 2.00 atm
Partial pressure of He = 0.450 atm
Partial pressure of Ar = 0.400 atm
Partial pressure of Xe = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(He) + P(Ar) + P(Xe)
2.00 atm = 0.450 atm + 0.400 atm + P(Xe)
2.00 atm = 0.850 atm + P(Xe)
P(Xe) = 2.00 atm - 0.850 atm
P(Xe) = 1.15 atm
