Boiling Point Elevation/Freezing Point Depression T = m K where, for freezing point depression: T = T(pure solvent) - T(solution) and for boiling point elevation: T = T(solution) - T(pure solvent) m = (# moles solute / Kg solvent) Kb = boiling point elevation constant. Kf = freezing point depression constant. Kb and Kf depend only on the SOLVENT. Below are some common values. Use these values for the calculations that follow.

(This question and the next 2 questions are breakdowns of the same question) A student John wanted to measure the molar mass of an unknown material (UM) via the boiling point change of a solvent. He chose a solvent, ethanol, that can dissolve the material and sugar. He wanted to use sugar (MW = 342.3 g/mol) as a reference sample to get an ebullioscopic constant for his system to reduce the effect of other measuring errors such as pressure, measuring errors, and impurity of the samples. He made 10 solutions each contain 100 g of ethanol and various amont of solute as list in the table. He fits the two sets of data and obtain the molar weight of the unknown materials. For this question answer the fitted boiling point of pure ethanol: ____ K. 4 sig. fig. Thre rest ? marks in the tale will be answered in the next two questions. Copy the data into Excel and use trendline to fit or calculate the average values for this and the next 2 questions. Sample # Sugar (g) B.P. (K) Sample # UM…

Referring to the Al-Si Eutectic diagram discussed on the Phase Diagrams-Lever Rule handout, calculate the mass fraction of the phase, silicon, given a sample with 51.7 wt% aluminum at 576.99 ˚C.
3. Refer to the phase diagram depicted below: When 7 moles of A and 3 moles of B are mixed at 50oC which is then cooled to 10oC the sample turns into two liquid phases, phase I has mole fraction xB=0.14 (see diagram below). Find the phase II mole fraction xB, and then calculate the ratio of amount of substance in phase I to that in phase II using Lever rule. Please enter your answer as a number with two decimals. for example, if the ratio you calculated is 2:3, you enter as 0.67
