Choose the most correct option.

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)________.

Options

5.41 %

3.54 %

4.53 %

53.4 %

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:

${\displaystyle {\text{M}}_2=\frac{{\text{W}}_2\text{RT}}{\pi \text{V}}}$

${\displaystyle \frac{{\text{W}}_2}{\text{V}}=\frac{\pi {\text{M}}_2}{\text{RT}}}$

${\displaystyle =\frac{7.65 \text{atm}\times 180 {\text{g mol}}^{-1}}{0.08205\text{atm}{\text{dm}}^3{\text{K}}^{-1}{\text{mol}}^{-1}\times 310\text{K}}}$

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