Assessment Brief
You
are studying an Alzheimer’s brain protein for Dr. Durrant which is a tau
protein. It is believed to have a mass
between 55,000 and 62,000 g/mol. You
have been given the task of determining its actual molecular mass. If you assume a mass of 58,500 g/mol, and
were to dissolve 5.00 mg in 1.00 mL water, calculate the freezing point
depression of this solution, boiling point elevation of this solution, the
vapor pressure change (from 23.76 Torr at 25°C) for the solution, the osmotic pressure
for the solution, and the height of a column of water corresponding to this
osmotic pressure. Which method would you
use to experimentally determine the molecular mass of this polymer, and why?
