Molality = \frac{n _{solute}}{W _{solvent}} \times 1000 100 = \frac{X _{solute} \times 1000}{X _{solvent} \times M _{solvent}} 100 = [\frac{X _{solute}}{1 - X _{solute}}] \times \frac{1000}{18} [1 - X_{solute}] 18 = 10 X_{solute} 18 = 28 X_{solute}

X_{solute} = \frac{18}{28} = \frac{9}{14} = 0.6428 = 0.643 = 64.3 \times 1 0^{- 2}
