Determine the freezing point of a 0.765 m solution of nitrobenzene in naphthalene. (given: naphthalene kf = 7.45o c kg/ mole and the pure freezing point is 80.3o c) report answers to one decimal place.

The freezing point of a 0.765 m solution of nitrobenzene in naphthalene is

Explanation:

Depression in freezing point is given by:

= Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte such as nitrobenzene)

= freezing point constant =

m= molality  = 0.765

Thus the freezing point of a 0.765 m solution of nitrobenzene in naphthalene is

the answer is option a.
