Question

Total pressure exerted by mixture of three gases A , B , C is 24 atm. If mole fraction of a gas A at 0.3 and mole fraction of remaining two gases is same then calculate the partial pressure in atm of each gas.

• A. 8.4
• B. 6.4
• C. 4.2
• D. 3.2

Answer 1

Answer: (A)

8.4

Partial pressure of gas = Mole fraction of gas$\times P_{Total}$

$=.35\times 24=8.4atm$

As the mole fraction of $B,C$ gas are same.
