a.) Calculate the molar mass of unknown "x" if: 1.60 g of unknown "x" dissolved in 100.0of cyclohexane produces a freezing point of -5.1 degree celsius (cyclohexane has a freezing point = 3.9 degree celsius and the molal freezing point constant is 18.0).
b.) How many mL of unknown "X" (density = 0.79 g/mL) needs to be dissolved in 50.0 g of water (Kb=0.512) to make the boiling point of the resulting solution to be 104.5 degree celsius if when unknown "X" dissolves in water to form 3 moles of ions for every mole of unknown "X"?
