Experiment 2 - Molar Mass by Freezing Point Depression Pre-Lab Assignment Name. Solve the problem below, which will be a good orientation to thte calculations you will be doing in this experiment. Instructions: Printout these pages and do the calculations indicated. Turn in completed pages at the beginning of the Lab. In an experiment similar to the one you will be doing this week, the freceing point of pure water was determined by plotting the temperature as a function of time. The freezing point was determined to be 0.021C. A sample of an unknown liquid having a volume of 39.0mL was then thoroughly mived with 225mL of deionized water. The liquid had a density of 0.790g/mL The resulting freezing point of the unknown in water was determined to be 4.25C. Kr for water is 1.86C/m. 1. Calculate T1 for water in this experiment Ty=Tf, water - Tf;olation 2. What is the molality of the solution of the unknown in water? (Tf=mKf) 3. How many moles of the unknown liquid are there in the soludion
