Calculate molal elevation constant for a solution containing 1.5 g solute dissolved in 250g g solvent,having elevation of boiling point 0.01. [ molecular wt. = 60]

A

0.1

B

0.01

C

0.5

D

0.005

Text Solution

Verified by Experts

The correct Answer is:
A

`K_(b) = (Delta T_(b) M_(B)W_(A))/( WB xx1000) =(10^(-2) xx 60xx 250)/( 1.5 xx 10^(3))=0.1 `
