You are studying ATCase regulatory chain for a research project. It is believed to have a mass between 15,000 to 20,000 g/mol. You have been given the task of determining its actual molecular mass. If you assume a mass of 17,000 g/mol, and were to dissolve 5.00mg in 1.00mL water, calculate the freezing point of this solution, boiling point of this solution, the vapor pressure change (from 23.76 torr at 25C) for the solution, the osmotic pressure of the solution, and the height of a column of water corresponding to this osmotic pressure. Which method do you use to experimentally determine the molecular mass of this polymer, and why?
