The increase in boiling point of a solution containing 0.6 gram Urea in 200 gram water is `0.50^@`C. Find the n-olal elevation constant

A

10 K kg mole

B

10 K kg `"mole"^(-1)`

C

1.0 K kg mole

D

100 K kg `"mole"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(b)=(Delta T xx M xx W_(0))/(1000xx W)=(0.5xx60xx200)/(1000xx0.6)`
`= "10 K kg mole"^(-1)`
