A 1.60-g sample of a mixture of naphthalene () and anthracene () is dissolved in 20.0 g of benzene (). The freezing point of the solution is 2.81 oC. What is the composition, as mass percent, of the sample mixture? The freezing point of pure benzene is 5.51 oC and its cryoscopic constant (Kf) is 5.12 oC kg mol-1.
