2. Suppose you just made a compound containing only boron and fluorine. To determine its molar mass you dissolve 0.176 g in 110.0 g of benzene and find that the freezing point of the solution is 4.77°C. (the freezing point of pure benzene is 5.50°C and K, for benzene is -4.90 °C/molal) If the compound contains 22.1% boron, what are the empirical and molecular formulas of the boron-fluorine compound?
