Relative lowering of vapour pressure of a dilute aqueous solution of glucose is found to be 0.018. Hence, elevation in boiling point is:(Given, that 1 molal aqueous urea solution boils at 00.54 oC at 1 atm pressure)
An aqueous solution freezes at -0.2°C. What is the molality of the solution. Determine also the-
(I) elevation in boiling point
(II) Lowering of vapour pressure
Given Kf=1.86°C Kg/mol Kb=0.512°C Kg/mol.
Vapour pressure of water=23.756 mm
