Question

The vapour pressure will be lowest for: (A)  0.1 M sugar solution (B)  0.1 M KCl solution (C)  0.1 M Cu(NO3)2 solution (D)  0.1 M AgNO3 solution

Vapour pressure of a solvent is lowered by the presence of solute in it. Lowering in vapour pressure is a colligative properly i.e. , it depends on the no. of particles present in the solution. Cu(NO3)2 give the maximum no. of ions (i.e.,3) so it causes the greatest lowering in vapour pressure of water.
