Explanation:

A. the above law is Raoulet's act

Po-P

____=X

Po

B. Relative lowering in vapour pressure of solution containing non-volatile solute is directly proportional to mole fraction of solute.

C. In consequence, the relative lowering of vapour pressure of a dilute solution of nonvolatile solute is equal to the mole fraction of solute in the solution. in the mixture (in the solution).
