Question
In the lab, a student follows the following steps to determine the freezing point and molality of a deicer solution.
(a) Using the data from the table, determine the molality of the deicer solution. molality = m CaCl2 (b) Based on the collected data, what is the van't Hoff factor? The Kf for water is 1.86 °
C/m.i = |
Expert Solution
Step 1
Given
- mass of CaCl2 = 9.57 g
- Volume of water = 58.6 mL = 58.6 g
Convert grams to kg using conversion factor : 1 kg = 1000 g
- mass of water (solvent) = 0.0586 kg
Required data -
- molar mass of CaCl2 = 110.98 g/mol
