Question

22. The molar elevation constant for water is 0.56
kkgmol-1
Calculute the boiling point of a solution made by dissolving 6g of urea in 200
of water.=



solution
m×W1000Kb​×w​
Given, Kb​=0.56Kkgmol−1,w=6.0g,W=200g,m=60
△T=200×601000×0.56×6.0​=0.28oC
Thus, the boiling point of solution =boilingpoint. of water +△T
=(100oC+0.28oC)=100.28oC
