### Solution

The osmotic pressure of blood is 7.65 atm at 310 K. An aqueous solution of glucose isotonic with blood has the percentage (by volume) 5.41%.

Explanation:

${\text{M}}_{2}=\frac{{\text{W}}_{2}\text{RT}}{\pi \text{V}}$

$\frac{{\text{W}}_{2}}{\text{V}}=\frac{\pi {\text{M}}_{2}}{\text{RT}}$

= 54.1 g dm-3 = 5.41 g cm-3 = 5.41%
