Question

1g of a non electrolyte solute dissolved in 50g of benzene lowered the freezing point of ben-
zene by 0.4K Find the molar mass of the solute ,K, for benzene =5.12Kkgmol-1​

Answer 1

Answer:256

Explanation:

Depression in freezing pt=Kf×molality

0.4=5.12×(1/m)×(1000/50)

m=5.12×1000/50×0.4

=256

Answer 2

Answer:256

Explanation:

Depression in freezing pt=Kf×molality

0.4=5.12×(1/m)×(1000/50)

m=5.12×1000/50×0.4

=256
