Urvashi Yadav · Accepted Answer

1 00 molal aqueous solution means that 1 mol of solute is dissolved in 1 Kg of water Number of moles of solute = 1 Number of moles of water = 1000/18= 55 556 mole fraction of solute = $\frac{n u m b e r o f m o l e s o f s o l u t e}{n u m b e r o f m o l e s o f s o l u t e + n u m b e r o f m o l e s o f s o l v e n t}$ mole fraction = $\frac{1}{1 + 55 556}$ = 0 01768 = 0 0177 so answer is 0 0177
