After adding non-volatile solute, freezing point of water decreases to -0.186^(@)C. Calculate Delta T_(b) if : K_(f) = 1.86 "K kg mol"^(-1) and K_(b) = 0.521 "K kg mol"^(-1)

Answer»

`0.521`
`0.0521`
`1.86`
`0.0186`

Solution :`DELTA T_(F)=K_(f)xx m rArr 0.186=1.86xx m`
So m = 0.1, Put the VALUE of m in `Delta T_(b)=K_(b)xx m`
`Delta T_(b)=0.521xx(0.1)=0.0521`
