But, if the bag is filled with a dye of large molecules, the dye cannot pass out into the water but water will pass into the dyecausing a permanent pressure difference. The two sides of the semipermeable membrane eventually achieve equilibrium due to this process. The general equation for gases applies to osmotic pressure: where = the osmotic pressure in atmosphere, n = the number of moles of solutes, R = the molar gas constant (0.082 litre-atmosphere/mol/), T = the absolute temperature, V = the volume in litres. Osmosis is the movement of water from an area of low concentration of solute to an area of higher concentration of solute. They are non-electrolytes. (2020, August 26). One liter of an aqueous urea solution contains 6 g of urea.
