Q. The molecular weight of a non-volatile solute can be determined by which method?

गैर-वाष्पशील विलेय का आणविक भार किस विधि द्वारा निर्धारित किया जा सकता है?

A
Depression in freezing point
हिमांक बिंदु पर अवसाद
B
Elevation in boiling point
क्वथनांक में ऊंचाई
C
Relative lowering of vapor pressure
वाष्प दबाव का सापेक्षिक रूप से कम होना
D
All of these
इन सब

Explanation

Molecular weight can be determined by colligative properties such as:

  • Depression in freezing point

  • Elevation in boiling point

  • Relative lowering of vapor pressure

  • Osmotic pressure

All depend on the number of particles and allow molecular weight calculation.
