Osmotic pressure of a $2\%$ $\mathrm{w}/\mathrm{v}$ solution of glucose is same as $5\%$ $\mathrm{w}/\mathrm{v}$ solution of a non-volatile non-electrolyte solute. The molar mass of the solute is:

Colligative properties have many practical uses, some of them may be:

I: Melting of snow by salt.

II: Desalination of seawater.

III: Determination of molar mass.

IV: Determination of melting point and boiling point of solvent actual practical uses are:

Consider the following terms ($\mathrm{m} =$molality):

$\mathrm{I} : {\mathrm{mK}}_{\mathrm{b}}$

$\mathrm{II} : {\mathrm{mK}}_{\mathrm{b}}\mathrm{i}$

$\mathrm{III} : \frac{∆{\mathrm{T}}_{\mathrm{b}}}{\mathrm{i}}$

$\mathrm{IV}: {\mathrm{K}}_{\mathrm{b}}$

Terms which can be expressed in degree (temperature) are

What is the normal boiling point of the solution represented by the phase diagram?
