The formula for Osmotic pressure is given by:
 Π = Osmotic pressure = i M R T
       i = 1  for non-electrolytic solutes.
       M = molar quantity of the solute = (1 / 185000) mol /  0.450 Liters
       R = universal gas constant = 8.314 J /K/mol
       T = abs Temperature = 273 + 37 ⁰C = 310⁰ K

  Π =  1.201201 * 10⁻⁵ * 8.314 * 310 = 0.030959 J / Litres
     = 0.030959 N-m / 0.001 m³
     = 30.959  N/m² or Pa
