The molal freezing point depression constant for benzene (C6H6) is 4.90 K Kg mol-1. Selenium exists as a polymer of the type Sex. When 3.26 g of selenium is dissolved in 226 g of benzene, the observed freezing point is 0.112C lower than that of pure benzene. The molecular formula of selenium is (atomic mass of Se = 78.8 g mol-1).
