Unformatted text preview: cyclohexane and dichlorobenzen cyclohexane mixture are approached to 7.0 C and 2.0 C, respectively. Density of dichlorobenzene is 0.7726g/mL at 25 C. Determine: A. The molarity of the dichlorobenzene solution. B. The freezing point constant, K f , of cyclohexane. 5 . 0.5g of an unknown compound is added to 10mL cyclohexane in the freezing point apparatus. The freezing point for pure cyclohexane and unknown compound cyclohexane mixture are approached to 7.0 C and 0.5 C, respectively. Density of dichlorobenzene is 0.7726g/mL at 25 C. Determine molecular mass of solute (Kf(clycohexane)=20 C Kg/mol)...
