(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.
