1. Reproduce the data from the data page and turn it in along with the graphs.
There are two portions of the curve, a cooling portion and freezing of the liquid.
Draw a trendline through each portion. The temperature at the point of intersection
is the freezing point of the solution.
2. Freezing point of unknown solution (°C) (from graph)
3. Freezing point depression for solution: AT (°C)
(Show Calculations)
4. Molality of Unknown solution (mol/kg)
(Show Calculations)
5. Molar Mass of unknown (g/mol)
(Show Calculations)
6. True Value of Molar Mass of Unknown (g/mol)
