What is the influence of added non-volatile solute on the boiling point of solvent ?

At 298 K, the vapour pressure of a solution of 7.5 g of non-volatile solute in 90 g of water is 2.8 kPa. If 18 g of water is added to this solution vapour pressure becomes solution the vapour pressure becomes 2.81 kPa at same temperature, the molar mass of solute in g mol^(-1) is

The vapour pressure of a solution containing non volatile solute is less than the vapour pressure of pure of solvent. Give reason.

Which of the following statements are correct (a) the boiling point of a solution is greater than pure solvent (b) the temperature where the vapour pressure of liquid equals to atmospheric pressure is called its boiling point (c) the vapour pressure of pure solvent is less than the vapour pressure of solution containing non volatile solute. (d) the temperature of liquid remained in the container after evaporation is more than before the evaparation

When some amount of non-volatile solute is dissolved in a solvent to prepare a dilute solution, the vapour pressure of the solvent is lowered and it is directly proportional to the mole fraction of solvent in the solution . Relative lowering in vapour pressure is equal to mole fraction of solute . Elevation in boiling point of solvent is a collgative property like lowering in vaour pressure of solvent in solution , K_(b) i.e., molal elevation constant is calculated by the formula, K_(b)=DeltaT_(b)// molality and also by the expression, K_(b)=RT_(b)^(2)//1000l_(v) where T_(b) is boiling point of solvent and I_(v) is latent heat of vapourisation for 1 gm solvent . Abnormal elevation is boiling point =iX elevation in boiling point in ideal solution where i=van't Hoff factor Lowering in vapour pressure in an experiment was found to be x mm of Hg. It is : Lowering in vapour pressure in an experiment was found to be x mm of Hg. It is
