Question
Calculate the freezing point of this solution Calculate the partial pressure of chloroform in this solution
: A solution is prepared by dissolving 20.0 g of Chloroform (CHC13) in 60.0 gram of benzene (C6H6). The total pressure of the mixture was measured to be 87.6 torr and the density of the solution was measured to be 0.856 g/mL. The following data are obtained for these two solvents. Chloroform Benzene Molar mass 119.4 g/mol 78.11 g/mol AHfusion 3.2 kJ/mol 9.9 kJ/mol AHvaporization 45.4 kJ/mol 30.7 kJ/mol Csolid 104 J/mol.K 118 J/mol.K Cliquid Cgas Normal boiling point Normal melting point 83.0 J/mol.K 135 J/mol.K 50.2 J/mol.K 104 J/mol.k 61.2 °C 80.1 °C -63.5 °C 5.5 °C Kf 4.70 °C/m 5.15 °C/m K 3.63 °C/m 2.53 °C/m
