QUESTION
Use the provided freezing point of the unknown compound/ TBOH
Use the provided freezing point of the unknown compound/ TBOH
solution from the plateau of the curves. Use your calculated Kf value (listed below) for TBOH and the measured ΔTf of the unknown compound (the change in freezing points) to calculate the molality of the unknown compound/ TBOH solution. Finally calculate the molecular weight of the unknown compound (MW = grams / moles).
Change in freezing points is 12 c
Kf value is 8.73 C kg/mole
TBOH used is 3.1579g and Unknown used is 0.5092g
