Camphor is often used in molecular mass determination because

1. it is readily available
2. it has a very high cryoscopic constant
3. it is volatile
4. it is solvent for organic substances

Correct answer: it has a very high cryoscopic constant

Solution

Camphor is used in molecular mass determination because its high cryoscopic constant allows for significant freezing point depression, making small changes in molecular mass easier to detect.
