A solution of carbon tetrachloride in benzene, C6H6, at 20 C has a total vapor pressure of 88.25 mmHg. (Assume that this solution is ideal) The vapor pressure of pure benzene at this temperature is 74.61 mmHg and its density is 0.8765 g/cm3, the vapor pressure of pure carbon tetrachloride is 91.32 mmHg and its density is 1.5940 g/cm3. What is the freezing point of the solution? Melting point (CCl4): -22.92 C Melting point (C6H6): 5.5 C K(CCl4): 2.65 C/m K(C6h6): 3.92 C/m
