Which of the following is incorrect relationship between given concentration terms? M = molarity; m = molality; d = density of solution in g / mL M^ = molar mass of solute ( g mol ⁻¹ ) ; M ^ = molar mass of solvent ( g mol ⁻¹ )X^ = mole fraction of solute; X ^ = mole fraction of solvent

Options

  1. AM = weight percentage (solute) 10 d M ^
  2. B1 m + M^ 1000 = d M
  3. Cm= 1000 x^ M^ X^
  4. DM= X^ d 1000 X^ M^ +X^ M^

Correct answer

D. M= X^ d 1000 X^ M^ +X^ M^

Step-by-step solution

aligned & m= M 1000 (1000 d-M^ M ) & 1 m = d M - M^ 1000 aligned aligned & M= n_ solute d 1000 w t_ solution = n_ solute d 1000 n_ solvent M^ +n_ solute M^ & M= x_ solute d 1000 x_ solvent M^ +x_ solute M^ aligned
