Question

what is the formula for relative lowering of vapouring pressure?​

Answer 1

Answer:

Relative lowering in vapour pressure

- definition

Then mole fraction of the solvent, X1 = N/(n+N) and mole fraction of the solute, X2= n /(N +n). Since the solute is non-volatile, it would have negligible vapour pressure. The vapour pressure of the solution is, therefore merely the vapour pressure of the solvent.
