Answer: The partial pressure of Argon , Neon and krypton are 48 kPa , 24 kPa and 8 kPa respectively.
Explanation:
According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

where,
= partial pressure of component A
= mole fraction of A
= total pressure
mole fraction of Ar = 

mole fraction of Ne = 

mole fraction of Kr =
