A solution was prepared by dissolving 0.1 mole of a nonvolatile solute in 0.9 moles of water. What is the relative lowering of vapour pressure of solution?

Options

  1. A0.9
  2. B0.5
  3. C0.1
  4. D0.05

Correct answer

C. 0.1

Step-by-step solution

Relative lowering of vapour pressure = P P aligned & P P = _ solute & P P = n _ solute n _ solute + n _ solvent = 0.1 0.1+0.9 = 0.1 1 & P P =0.1 aligned
