**DrBob222**, Tuesday, September 14, 2010 at 12:02ammoles glycerin = grams/molar mass

solve for moles glycerin.

molality = mole/kg solvent

solve for molality

delta T = K*m

solve for delta T, then freezing point.

**lisa**, Wednesday, September 15, 2010 at 7:42pmi tried to solve it on my own but im confused about the last part, this i what i have so far..

moles of glycerin= 50.0/92.10=0.54

molality=0.54/0.200=2.7

is that right?

im a little confused about the numbers im supposed to use for step 3...
