The molal depression constant for water ...

The molal depression constant for water is `1.86^(@)C`. The freezing point of a `0.05-molal` solution of a non-electrolyte in water is

Text Solution

Verified by Experts

`Deltat_(f) =` molability `xx K_(f)`
`= 0.05 xx 1.86 = 0.093^(@)C`
`(T_(f))_(s) = T_(0) -0.093 = 0-093`
`(T_(f))_(s) = -0.093^(@)C`
