π=CRT 7.40=n× 0.0821 × 300 π=(n/v)RT n=(7.4/0.0821 × 300) =0.3

Q. Osmotic pressure of blood is 7.40 atm at $2 7^{\circ} C$ . Number of mol of glucose to be used per L for an intravenous injection that is to have the same osmotic pressure as blood is:

$0.3$

$0.2$

$0.1$

$0.4$

$π = CRT$
$7.40 = n \times 0.0821 \times 300$
$π = \frac{n}{v} RT$
$n = \frac{7.4}{0.0821 \times 300}$
$= 0.3$
