The osmotic pressure is a colligative property which depends upon the number of molecules and not the type of molecules
The relation between osmotic pressure and concentration is
πV = nRT
where
π = Osmotic pressure [ unit atm] = ?
V = volume
n = moles
R = gas constant = 0.0821 L atm / mol K
T = temperature = 20°C = 20 + 273.15 K = 293.15 K
also
Molarity = moles / Volume
So
Molarity = n/V = 5.5 M
Putting values
π = MRT
π = 5.5 X 0.0821 X 293.15 = 132.37 atm
Osmotic pressure of given glucose solution will be 132.37 atm
