Explanation:
Relation between total pressure and mole fraction is as follows.
where, = partial pressure of gas 1
= mole fraction of gas 1
= total pressure of the gases
Also, it is known that = 1
or,
It is given that total pressure of gas mixture is 0.51 atm and partial pressure of helium is 0.32 atm.
Hence, calculate the mole fraction of helium gas present in the given mixture as follows.
0.32 atm =
= 0.63
As, = 1
so,
= 1 - 0.63
= 0.37
Hence, calculate the partial pressure of Ne as follows.
0.3084 atm =
= 0.834 atm
Thus, we can conclude that the partial pressure of the Ne in the mixture is 0.834 atm.
