Mole fraction of solute in it's 2 molal aqueous solution is

Options

  1. A28.775
  2. B0.034
  3. C0.054
  4. D0.018

Correct answer

B. 0.034

Step-by-step solution

No. of moles of solute =2 Mass of solvent =1 ~kg Since it is an aqueous solution, thus the solvent must be water. Moles of solvent = 1000 18 =55.5 moles Mole fraction of solute = 2 57.5 =0.0347
