The osmotic pressure of blood is 7.40 atm. at $27°C$. Number of mole of glucose to be used per liter for an intravenous injection that is to have the same osmotic pressure as blood is

Given data : It is given to identify the osmotic pressure of blood is 7.40 atm. at $27°C$. Number of mole of glucose to be used per liter for an intravenous injection that is to have the same osmotic pressure as blood is

Explanation :

$\mathrm{\pi }$ represents osmotic pressure, which is computed as $n=\frac{\pi V}{RT}$
Where $\mathrm{\pi }$ is 7.40 atm, V is 1L, R is 0.0821, and T is $27°C$=300K. The value of n is found to be

$n=\frac{7.40\times 1}{0.0821\times 300}=0.3$
Hence, the correct option (C).0.3
