Mole fraction of the solute in a 1.00 molal aqueous solution is

Options

  1. A0.0177
  2. B0.0344
  3. C1.7700
  4. D0.1770

Correct answer

A. 0.0177

Step-by-step solution

1.00 molal aqueous solution =1.0 mole in 100 ~g water n_ solute =1 ; W_ solvent =1000 ~g . aligned & n_ solvent = 1000 18 =55.56 & X_ solute = 1 1+55.56 =0.0177 aligned
