Question

How many grams of glucose (C6H12O6) should be used to make 1 Liter of an intravenous solution to match the osmotic pressure of blood (7.65 atm) at 37 °C?

Answer #1

Osmotic pressure is expressed by the formula:

Π = iMRT

where

Π is the osmotic pressure in atm

i = van 't Hoff factor of the solute.

M = molar concentration in mol/L

R = universal gas constant = 0.08206 L·atm/mol·K

T = absolute temperature in K

van 't Hoff factor is 1 for glucose

Absolute temperature = 310K

Concentration of glucose =

Π = iMRT

M = Π/iRT

M = 7.65 atm/ 1 x 0.08206 L·atm/mol·K x 310

M = 0.301 mol/L

The amount of sucrose per liter

M = mol/Volume

mol = M·Volume

mol = 0.301 mol/L x 1 L

mol = 0.301 mol

molar mass of glucose = 180 g/mol

mass of glucose = 0.301 mol x 180 g/1 mol

mass of glucose = 54.1 g

**54.1 grams per liter of glucose to be used for an
intravenous solution to match the 7.65 atm at 37 °C osmotic
pressure of blood.**
