Relaion between molal elevation constant and molaltiy is given as-
increment T subscript b equals m cross times K subscript b 0.126 equals 2.52 cross times K subscript b m equals fraction numerator 0.126 over denominator 2.52 end fraction M o l a l i t y equals space 0.05 space m o l space divided by space K g
