At `25^(@)` C, the vapour pressure of methyl alcohol is `96.0` torr. What is the mole fraction of `CH_(3)OH` in a solution in which the (partial) vapor pressure of `CH_(3)OH` is `23.0` torr art `25^(@)` C ?

Text Solution

Verified by Experts

`chi_(CH_(3)OH)=(P_(CH_3OH))/(P_(CH_(3)OH)^(0))=23/96=0.24`
