Assume a living cell with

0.9 \%(\omega / \omega)

of glucose solution (aqueous). This cell is immersed in another solution having equal mole fraction of glucose and water. (Consider the data upto first decimal place only) The cell will :

Options

Ashow no change in volume since solution is $0.9 \%(\omega / \omega)$
Bshrink since solution is $0.5 \%(\omega / \omega)$
Cswell up since solution is $1 \%(\omega / \omega)$
DNone of these

Correct answer

D. None of these

Step-by-step solution

Living cell

=0.9 \mathrm{gm}

in 100 gm of solution

\% \mathrm{w} / \mathrm{w}=0.9

Solution is have equal moles of glucose and water

=0.5

Weight of solution

=0.5 \times 180+0.5 \times 18=99 \mathrm{gm}

\% \mathrm{w} / \mathrm{w} \simeq 90 \%

Concentrated solution = Cell will shrink.
