Q.

Assume a living cell with 0.9% (ω/ω) 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 :                [2025]

1 shrink since solution is 0.5% (ω/ω)  
2 shrink since solution is 0.45% (ω/ω) as a result of association of glucose molecules (due to hydrogen bonding)  
3 swell up since solution is 1% (ω/ω)  
4 show no change in volume since solution is 0.9% (ω/ω)  

Ans.

(4)
