fert-Butyl alcohol is a solvent with a Kf of 9.10C/m and a freezing point of 25.5C. When 0.807g of an unknown colorless nonelectrolyte liquid was dissolved in 11.6g of tert-butyl alcohol, the solution froze at 15.3C Which of the following is most likely the identity of this unknown liquid? View Available Hint(s) ethylene glycol (molar mass =62.07g/mol) 1 -octanol (molar mass =130.22g/mol) glycerol (molar mass =92.09g/mol) 2-pentanone ( molar mass =86.13g/mol) 1-butanol (molar mass =74.12g/mol) Part B A protein subunit from an enzyme is part of a research study and Jeds to be characterized. A total of 0.180g of this subunit was dissolved in enough water to produce 2.00 mL of solution. At 28C the osmotic pressure produced by the solution was 0.138atm. What is the molar mass of the protein? Express your answer with the appropriate units
