Question

it is difficult to measure solution temperatures with an accuracy of better than 0.01 degrees C. 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?

A. no, it should not be possible because the change in temperature will be too large to measure correctly

B. no, it should not be possible because the change in temperature will be too large to measure accurately.

C. no, it should not be possible because there is no freezing point depression for aqueous protein solutions

D. no, it should not be possible because freezing point depressions are not directly related to molar masses

Explanation / Answer

D. no, it should not be possible because freezing point depressions are not directly related to molar masses
