Q. Mole fraction of the solute in $1$ molal aqueous solution is

AIPMTAIPMT 2005Solutions

Solution:

One molal aqueous solution contains $1$ mole of the solute in $1000\, g$ of $H_2O \, i.e.$, $1000/18$
= $55.55$ moles of water
$\therefore $ mole fraction of the solute = $\frac{1}{1 + 55.55}$
= $0.018$.
