Calculate the molar of solute when 1.5 gram non volatile solute dissolved on 100 mL solvent having density 0.8 g lowers its freezing point by 0.75K (Freezing point depression constant for solvent is 5 K kg )

Answer: (A)

Solution

Mass of solvent = volume density = g kg. Molar mass of a non-volatile solute from freezing point depression: $ = = Missing argument for \dfrac\dfrac{5 × 1.5 × 1000}{0.75
