Question

The mole fraction of glucose $(C_{6} H_{12} O_{6})$ in an aqueous binary solution is 0.1. The mass percentage of water in it, to the nearest integer, is ___________.

Moderate

Solution

m. f. of glucose $= \frac{m o l e s o f g l u \cos e}{(m o l e s o f g l u \cos e + m o l e s o f H_{2} O)}$
$0.1 = (\frac{1}{10}) = (\frac{1}{1 + 9})$
So glucose moles = 1, (h glucose) ${hH}_{2} O = 9$
$\begin{array}{l} W glucose = 1 \times 180 grm & {WH}_{2} O = 9 \times 18 grmas \end{array}$
$\begin{array}{l} Mass % of H_{2} O = (\frac{ω H_{2} O \times 100}{ω H_{2} O + ω glucose}) \\ = (\frac{9 \times 18 \times 100}{(9 \times 18) + 180}) = (\frac{162 \times 100}{342}) = 47.368 \end{array}$
