Question

The osmotic pressure of blood is 7.7 atm at 25°C. What concentration of glucose, C6H12O6, is isotonic (same osmotic pressure) with blood?

Answer 1

The problem wants you to determine what concentration of glucose would produce a solution that has the same osmotic pressure as blood at

25

∘

C

.

As you know, osmotic pressure is defined as the pressure required to prevent the flow of water across a semi-permeable membrane from a region of lower solute concentration into a region of higher solute concentration
