5 mL of acetone is mixed with 100mL of `H_(2)O`. The vapour pressure of water above the solution is

Options

A. equal to the vapour pressure of pure water
B. equal to the vapour pressure of the solution
C. less than the vapour prssure of pure water
D. more than tha vapour pressure of pure water

Answer

C

Explanation

V.P. of any component in the solution = mole fraction of the component x V.P. of that component in the pure state and mole fraction is always lt 1.
