Answer:
P(total) = 6.7 atm
Explanation:
Given data:
Partial pressure of N₂ = 3.5 atm
Partial pressure of O₂ = 2.8 atm
Partial pressure of Ar = 0.25 atm
Partial pressure of He = 0.15 atm
Total pressure = ?
Solution:
According to the Dalton law of partial pressure,
"The total pressure inside the gas cylinder having mixture of gases is equal to the sum of partial pressures of individual gas present in it"
Mathematical expression:
P(total) = P₁ + P₂ + P₃ + .........Pₙ
Now we will determine the total pressure of given gases.
P(total) = P₁ + P₂ + P₃ + P₄
P(total) =P(N₂) + P(O₂) + P(Ar) + P(He)
P(total) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm
P(total) = 6.7 atm
