When 18 g of ethylene glycol C2H6O2 is dissolved in 150 g of pure water, the freezing point of the solution is

_C . (The freezing point depression constant for water is 1.86C kg)

what i tried was 18/62 to find the moles. then i got .29/.150 to solve for the molality. then i got (.9350)(1.86) to solve for the temperature which is 3.6. i keep getting it wrong im i doing it right? please help. thanks
