Answer:
P(Ar) = 358.8 mmHg
Explanation:
Given data:
Total pressure of gas = 1380 mmHg
Moles of CO₂ = 1.27 mol
Moles of CO = 3.04 mol
Moles of Ar = 1.50 mol
Partial pressure of Ar = ?
Solution:
Formula:
P(Ar) = [n₁/nt] Pt .........(1)
n₁ = moles of Ar
nt = total number of moles
Pt = total pressure
Now we will calculate the total number of moles.
nt = 1.27 mol +3.04 mol +1.50 mol
nt = 5.81 mol
Now we put the values in formula (1)
P(Ar) = [n₁/nt] Pt
P(Ar) = [1.50/5.81] 1380 mmHg
P(Ar) = 0.26 ×1380 mmHg
P(Ar) = 358.8 mmHg
