partial pressure
Homework Answers
Use the formula P1 = Ptotal . X1
Where P1 = partial pressure of a gas, Ptotal = total pressure of gas mixture, and X1 = mole fraction of a gas
The problem tells you Ptotal = 1560 mmHg
Find the mole fraction by dividing the moles of Xe by the total moles
X1 = 1.75 / (1.75 + 1.50 + 2.65)
X1 = 1.75 / 5.90
X1 = 0.297
Plug in the variables into P1 = Ptotal . X1
P1 = (1560)(0.297)
P1 = 463 mmHg <-- partial pressure of Xe
