    Given,

    Mass of solute, glucose = 36 g

    Mass of solvent, water = 250 g

    Molar mass of glucose = 180 g/mole

    Molality : It is defined as the number of moles of solute present in the one kilogram of solvent.

    Formula used :

    where,

     = mass of solute, glucose

     = mass of solvent, water

     = molar mass of solute, glucose

    Now put all the given values in the above formula, we get

    Therefore, the molality of solution is, 0.8 mole/Kg

    1Thank You
