The freezing point of pure benzene was measured as 5.49 °C. With the same benzene and the same equipment, the freezing point of a solution containing 6.60 g of an unknown molecular compound in 140 g of benzene was found to be 2.35 °C. The cryoscopic constant, Kf, for benzene is 5.12 °C kg/mol. Calculate the mole weight of the unknown.

▸ 103 g/mol

▸ 76.9 g/mol

▸ 44.0 g/mol

▸ 28.9 g/mol

▸ 17.4 g/mol
