Question

) The osmotic pressure of blood is 7.65 atm at 270C. How much glucose should be used per litre to prepare an intravenous injection that has the same osmotic pressure as blood?

Answer 1

Answer:

The osmotic pressure is given by Π=CRT

Here, C is the molar concentration, R is the ideal gas constant (0.08206 L atm / mol . K) and T is the absolute temperature.

Now,

7.65=C×0.08206×(273+37)

∴C=0.3 M

⇒1 L of the solution will contain 0.3 moles of glucose. The molar mass of glucose is 180 g/mol.

This corresponds to 0.3×180=54.0 g of glucose.
