Osmosis occurs when two solutions of different concentrations are separated by a semipermeable membrane. The membrane allows solvent particles, but not solule particles, to pass through. Thus, the solvont moves toward the solution of higher concentration (to dilute it) until the two solutions have the same concontration, or unti gravity Crertakes the osmobic pressure. II. The osmotic presture between a solution and pure solvent depends on the number of solute particles and thus: is a colligative property it can be expressed as =MRTwhereM is the total molarity of the solute particles, R=0.08206Latm/(K - mol ) is the gas constant, and T is the Kelvin temperature.
