The vapour pressure of methyl alcohol a...

The vapour pressure of methyl alcohol at `298 K` is 0.158 bar. The vapour pressure of this liquid in solution with liquid `B` is 0.095 bar. Calculate the mole fraction of methyl alcohol in the solution if the mixture obeys Raoult's law.

Text Solution

Verified by Experts

The correct Answer is:
0.601
Mole fraction of A in solution ` = (0.095)/(0.158) = 0.601`
