) A solution is made from 87.3 of naphthalene (Molar mass 128.17 g/mol) and 3 liters of benzene (density 0.879 g/mL). For this problem you can conceder the naphthalene to be non-volatile. The temperature of the solution is 25 C.

a. What is the molality of this solution?

b. The Freezing point constant for benzene is Kf=5.12 C/m and its normal freezing point is 5.5 C, Whatâs the freezing point of the solution?

c. What/s the osmotic pressure of this solution, assuming that there is no change I volume of the benzene when the naphthalene is added?
