▼ Part A tert-Butyl alcohol is a solvent with a Kf of 9.10 °C/m and a freezing point of 25.5 °C. When 0.807 g of an unknown colorless nonelectrolyte liquid was dissolved in 11.6 g of tert-butyl alcohol, the solution froze at 15.3 °C.Which of the following is most likely the identity of this unknown liquid? ► View Available Hint(s) ethylene glycol (molar mass = 62.07 g/mol) 1-octanol (molar mass = 130.22 g/mol) glycerol (molar mass = 92.09 g/mol) 2-pentanone (molar mass = 86.13 g/mol) 1-butanol (molar mass= 74.12 g/mol) Submit Part B A protein subunit from an enzyme is part of a research study and needs to be characterized. A total of 0.140 g of this subunit was dissolved in enough water to produce 2.00 mL of solution. At 28 °C the osmotic pressure produced by the solution was 0.138 atm. What is the molar mass of the protein? Express your answer with the appropriate units. ► View Available Hint(s) Value Submit Units ?
