Solutions

The freezing-point depression constant (KfK_f) of benzene is 5.12 K kg mol−15.12\ \mathrm{K\,kg\,mol^{-1}}. The freezing-point depression for a solution of molality 0.078 m containing a non-electrolyte solute in benzene is (rounded to two decimal places):

  1. A.0.20 K
  2. B.0.80 K
  3. C.0.40 K✓
  4. D.0.60 K

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
