Which of the following physical properties is used to determine the molar mass of a polymer solution

Macromolecules like proteins and polymers have extremely high molecular weights.

The molarity of the solution is employed in place of molality in the osmotic pressure method, which has the benefit over other methods in that pressure measurement occurs at temperatures close to room temperature. Even for relatively diluted solutions, its size is substantial in comparison to other colligative qualities.

The characteristics of macromolecules remain unchanged at room temperature. Osmotic pressure can therefore be used to calculate the polymer's molecular mass.
