Colligative Properties Worksheet Key
Greetings everyone! Hope you learned lots about how solutes cause the freezing point to lower on a solution. Here are the answers to your worksheet distributed earlier this week so that you can check to ensure that you are doing the problems correctly. Note: I used 0.512 C/m as my Kb in all of my calculations.
1) new FP -3.72 deg C new BP 101.04 deg C
2) molality = 0.1 m and moles = 0.01 moles
molecular formula is S8
3) new FP -2.14 deg C
4) new FP -5.72 deg C new BP 101.57 deg C
5) for sucrose new BP is 100.314 deg C
for sodium chloride new BP is 101.23 deg C
6) new BP 101.15 deg C
7) CH3CH2OH < NaF < CaCl2 < K3PO4
lowest to highest BP
8) 0.0538 mol
9.68 g glucose
I trust that you are working problems in the text as well. Own your learning - invest in yourself!
