Glucose is added to `1` litre water to such an extent that `(Delta T_(f))/(K_(f))` becomes equal to `(1)/(1000)`, the weight of glucose added is:

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaT_(f)=K_(f)xx"Molality"=K_(f)xx(wxx1000)/(mxxW)`
`:.(DeltaT_(f))/(K_(f))=(wxx1000)/(mxxW)`
or`(1)/(1000)=(wxx1000)/(180xx1000):.w=0.18g.`
