Elevation in boiling point was 0.52^(@)C...

Elevation in boiling point was `0.52^(@)C` when 6 g of a compound X was dissolved in 100 g of water. Molecular weight of X is (`K_(b)` of water is `5.2^(@)C` per 100 g of water)

A

120

B

60

C

600

D

180

Text Solution

Verified by Experts

The correct Answer is:
b
We know that
`m = (100K_(b).w)/(DeltaT_(b).W)`
`= (100xx5.2xx6)/(0.52xx100) = 60`
