Biphenyl freezing point
WebTranscribed Image Text: 4. 0.422g of an unknown complex compound was dissolved in 2.12g of pure biphenyl, the freezing point of biphenyl was reduced by 10.310C. If the molal freezing point depression constant (Kf) for biphenyl is 8.15 oC/m, the molar mass of the unknown complex compound is: * WebMolar Mass Determination from Freezing Point Depression This is a new procedure. The purpose of implementing this procedure is to reduce waste and use less toxic materials. Previously, compounds such as p-dichlorobenzene, biphenyl, benzil, and naphthalene were used. As these compounds are toxic and therefore potentially hazardous, they have ...
