5.
What is relative lowering of vapour pressure? How is it válto
determine the molar mass of solute?​

Answer 1

Answer:

Relative molar masses can be determined by measuring colligative properties for a dilute solution of a non-ionized solute. ... As per this law, the relative lowering of the vapor pressure of a dilute solution is equal to the mole fraction of the solute present in dilute solution
