To observe an elevation of boiling point...

To observe an elevation of boiling point of `0.05^(@)C`, the amount of a solute (molecular weight = 100) to be added to 100 g of water `(K_(b) = 0.5)` is

A

2 g

B

`0.5g`

C

1 g

D

`0.75g`

Text Solution

Verified by Experts

The correct Answer is:
C
Elevation of boiling point,
`DeltaT_(b)=(wxxK_(b)xx1000)/(MxxW)`
`0.05=(wxx0.5xx1000)/(100xx100)orw=1g`
