1.	Consider following figure and answer the questions at the end of it. Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperature and showing elevation in boiling point. Elevation in boiling point of an aqueous urea solution is 0.52^(@). (K_(b) = 0.52^(@) mol^(-1)kg). Hence, mole fraction of urea in this solution is
