Question
Why is the osmotic pressure measurement preferred for determining molecular mass of proteins?
Solution
Proteins are high molecular mass materials. The magnitude of a colligative property depends inversely on the molecular mass. For high molecular mass proteins the only colligative property which has a measurable magnitude is the osmotic pressure.
Therefore, to determine the molecular mass of proteins, osmotic pressure is preferred.
Therefore, to determine the molecular mass of proteins, osmotic pressure is preferred.
