[CHM 112] Lab Questions

[Andrew J. Pounds]

No - not an equation this time -- you experimentally determine the value 
of the freezing point graphically.

I would like the unknown number and the molar mass of your unknown in 
the big box.

Yes -- for the second trial with the unknown the solute mass it the sum 
of the mass from the first experiment and what you added in the second 
trial.
