A sugar solution boils at `101^(@)C`. The molality of the sugar solution is (Given, `K_(b) = 0.52^(@)C kg mol^(-1)`)

A

1.84 m

B

1.92 m

C

2.02 m

D

4.02 m

Text Solution

Verified by Experts

The correct Answer is:
b
We know that `DeltaT_(b) = i.K_(b).m` (Here, I =1)
`:. (101 -100) = 0.52xxm`
`:.` Molality (m) `= (1)/(0.52) = 1.92`
