Answer:

Density = 1.25gmL-1.

Let us find molality.Molality = Number of moles of solute / Mass of solvent in Kg.

Number of moles of solute  = Mass of glucose / Molar mass of glucose.

Molar mass of glucose Na + = 23  g /mol.

Number of moles 92 gm Na +==  92/23  = 4 moles.Molality  =4 M.

hope it will help you dear....
