Question

It is difficult to measure solution temperatures with an accuracy of better than 0.01 degreeC. Which of the following is the most reasonable statement about using freezing point depression in an aqueous solution to determine the molar masses of biomolecules such as proteins? Yes, it should be possible to determine the molar mass of a typical potein accurately using freezing point depression. No, it should not be possible because the change in temperature will be too large to measure accurately. No, it should not be possible because the change in temperature will be too small to measure accurately. No, it should not be possible because there is no freezing point depression for aqueous protein solutions. No, it should not be possible because freezing point depressions are not directly related to molar masses.

Explanation / Answer

Yes, it should be pretty accurate since

Tf = -KF * m

where m = mol / kg solvent

and

Molar Mass = mass/mol

choose "YES" first option
