Question
Equal masses of methane and oxygen are mixed in an empty container at 25oC. The fraction of the total pressure exerted by oxygen is
Options
A.
B.
C.
D.
Solution
Let the mass of methane and oxygen is w
mole fraction of oxygen =
Let the total pressure be P
The pressure exerted by oxygen (partial pressure) = XO2 × Ptotal
⇒ P ×
Hence, (3) is correct.
