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

Answer»

`-1.86^(@)C`
`-0.93^(@)C`
`-0.093^(@)C`
`0.93^(@)C`

Solution :`DELTA T_(F)=K_(f)xx` MOLALITY `=1.86xx0.05=0.093^(@)C`
Thus FREEZING point `=0-0.093=-0.093^(@)C`.
