Calculate the molal elevation constant for water given that 0.2 molat solution of non-volatile and non-electrolyte solute increases the boling point of water by0.104 K.

Text Solution

Verified by Experts

`DeltaT_(b)=K_(b)xxmorK_(b)=(DeltaT_(b))/m`
`m=0.2m,DeltaT_(b)=0.104 K`
`K_(b)=((0.104 K))/((0.2m))=0.52 km^(-1)or 0.52 K kg mol^(-1)`
