On single-component phase diagrams, the phase rule is given by f= 3 - p. This equation means that if f = 1, the region containing the indicated phases is a point. True False
The sedimentation coefficient for a protein in solution is determined to be 4.3 S, and the diffusion coefficient to be 5.5x10-11 m2s-1 (vb = 0.74 mLg-1; density = 1.0 gmL-1; and viscosity = 1.0x10-3 Pas-1). Use this information to calculate the molar mass (kgmol-1) of the protein. Assume temperature of 298 K.

(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.
