Answer:
1.6 atm
Explanation:
Data obtained from the question include:
Mole of Gas X = 2 moles
Mole of Gas Y = 6 moles
Total pressure = 2.1 atm
Partial pressure of Y =?
Next, we shall determine the mole fraction of of Gas Y.
This can be obtained as shown below:
Total mole = mole of Gas X + mole of Gas Y
Total mole = 2 + 6 = 8 moles.
Mole fraction of Gas Y = mole of Gas Y/ Total mole
Mole fraction of Gas Y = 6/8 = 0.75
Now, we can calculate the partial pressure of Gas Y as follow:
Mole fraction of Gas Y = 0.75
Total pressure = 2.1 atm
Partial pressure of Gas Y =?
Partial pressure of Gas Y = mole fraction of Gas Y x Total pressure
Partial pressure of Gas Y = 0.75 x 2.1
Partial pressure of Gas Y = 1.6 atm
Therefore, the Partial pressure of Gas Y is 1.6 atm.
