NEVERMIND MY FAIL I FIGURED IT OUT 1. The problem statement, all variables and given/known data Find theoretical freezing point of depression. It's 30.07g NaCl(s) dissolved into 100.08 g of water/ice Kf= -1.86 etc.. 2. Relevant equations Freezing Point Depression = Kf * i * m 3. The attempt at a solution I have van't hoff factor (i) = 2 but i calculuated 1.0943 mol NaCl / .10008 kg water = molality = 10.934 molal/kg I end up getting -40 C for the answer? When I do the same operation for sucrose, calcium chloride (dihydrate) and aluminum chloride (hexahydrate) i get numbers in the hundreds, what am i doing wrong.
