Question

An artificial cell is made by encapsulating 0.2 M glucose solution within a semipermeable membrane. The osmotic pressure developed when the artificial cell is placed within a 0.05 M solution of NaCl at 300 K is  bar. (nearest integer).

[Given: ] Assume complete dissociation of NaCl

Strategy:
 Net osmotic pressure across a semipermeable membrane is the difference between the osmotic pressures of the two solutions (). Remember to use the van't Hoff factor for electrolyte solutions like .

Step 1: Calculate  for the glucose solution (inside)
- ,

Step 2: Calculate  for the  solution (outside)
- ,

Step 3: Determine net pressure developed

Step 4: Express as 
.
