QAIPMT-2006-Ch-2424: NEET 2006 Chemistry - Class 12 AIPMT-2006-Ch-2424 Solution: 1.00 g of a non-electrolyte solute (molar mass 250 g…

1.00 g of a non-electrolyte solute (molar mass 250 g mol

^{-1}

) was dissolved in 51.2 g of benzene. If the freezing point depression constant,

K_f

of benzene is 5.12 K kg mol

^{-1}

, the freezing point of benzene will be lowered by

Step-by-Step Verified Solution

Molality of non-electrolyte solute = 1 250 _ 0.0512 = 0.0781 m _ T f = k f m = 5.12 _ 0.0781 = 0.4 K
