Experiment questions:
Experiment 1 results
mass of beaker:116.944 g
mass of dodecanoic:11.629 g
hot water: 175 C
warm water: 10 C
Average Fressing pt of Dodecanoic = 42.7
Experiment 2 results:
Unknown C solution mass: 2.091g
Hot water: 175C
warm water: 10C
average FP of UK C 71.8C
From Part 2, take the average of the two freezing point experiments to get the freezing point for the dodecanoic acid solution and determine T, the magnitude of the freezing-point depression (a positive number) for the solution of the unknown solute and the dodecanoic acid.
Applying the formula and dividing, (the van't Hoff factor I is equal to 1 for
these compound because they are nonelectrolytes).

Jessica, I don't understand the problem.
That's the same issue i'm having. This is directly from my printed lab sheet.
