    Addition of non-volatile solute to a solvent always inceases the colligative properties such as osmotic pressure, `DeltaP, DeltaT_(b)` and `DeltaT_(f)`. All these colligative properties are direactly propertional to molality if solutions are dilute. The increase in colligative properties on addition of non-volatile solute is due to incease in number of solute particles.
    For different aqueous solutions of `0.1 N NaCl, 0.1 N` urea, `0.1 N Na_(2)SO_(4)` and `0.1 N Na_(3)PO_(4)` solution at `27^(@)C`, the correct statement are :
    `1g` mixture of glucose and urea present in `250 mL` aqueous solution shows an osmotic pressure of `0.74` atm at `27^(@) C`. Assuming solution to be dilture, which are correct ?
    (P) Percentage of urea in solute mixture is `17.6`
    (Q) Relative lowering in vapour pressure of this solutions is `5.41 xx 10^(-4)`.
    (R) The solution will boil at `100.015^(@)C`, if `K_(b)` of water is `0.5 K “molality”^(-1)`
    (S) If glucose is replaced by same amount of sucrose, the solution will show higher osmotic pressure at `27^(@)C`
    (T) If glucose is repalced by same amount of `NaCl`, the solution will show lower osmotic pressure at `27^(@)C`.
    A. 1,2,3
