The freezing point of pure benzene was measured as 5.49 °C. With the same benzene and same equipment, the freezing point of a solution containing 6.582 g of an unknown molecular compound (sold in the store as "moth crystals") in 100.203 grams of benzene was found to be 3.48 °C. The cryoscopic constant, Kf, for benzene is 5.12 °C kg/mole. Calculate the molar mass weight of the unknown.

▸ 37.5 g/mol

▸ 16.7 g/mol
