alleryOsmotic pressure is especially useful for finding the molar mass of:
ALight metals
BBiomolecules
CSimple salts
DNoble gases
Answer & Solution
Correct answer: B. Biomolecules
1. Some substances are unstable at higher temperatures.
2. Polymers among them also dissolve poorly.
3. So osmotic pressure suits biomolecules particularly well.
