Calculate the molal elevation constant of water evaporates at `100^(@)"C"` with the absorption of `536` calories per gm `(R=2 "cals")`

A

`0.519^(@)"C"`

B

`0.0519^(@)"C"`

C

`1.519^(@)"C"`

D

`2.519^(@)"C"`

Text Solution

Verified by Experts

The correct Answer is:
A
Molal elevation constant of the solvent.
`"K"_(b)=("RT"_(b)^(2))/(l_("v")xx100)=(2xx373xx373)/(536xx1000)=0.519^(@)"C"`
