Which colligative property is most suitable for determining the molar mass of macromolecules such as proteins in solution?
Answer and explanation
Correct answer: Osmotic pressure
Osmotic pressure is most suitable for determining the molar mass of proteins and other macromolecules because it can be measured in very dilute solutions. The method does not require heating or freezing, which helps prevent denaturation of sensitive biomolecules. Using π = CRT, the concentration of the macromolecule can be related to its molar mass. The other changes may be too small in dilute solutions. Therefore, option D is correct.
