Answer: 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
