osmole The standard unit of osmotic pressure. The osmole is equal to the molecular weight of the dissolved substance expressed in grams divided by the number of particles or IONS into which each molecule of the substance dissociates in solution.

Osmotic concentration, formerly known as osmolarity, [1] is the measure of solute concentration, defined as the number of osmoles (Osm) of solute per litre (L) of solution (osmol/L or Osm/L).

Jan 22, 2021 · Osmoles are measured concentrations of dissociated ions in a solution that contribute to osmotic pressure. What is Osmolarity? To understand osmolarity, we need to know about how water and molecules travel across cell membranes. This requires basic knowledge of several associated terms.

May 9, 2019 · An osmole is a unit of measurement that describes the number of moles of a compound that contribute to the osmotic pressure of a chemical solution. The osmole is related to osmosis and is used in reference to a solution where osmotic pressure is …

The meaning of OSMOL is a standard unit of osmotic pressure based on a one molal concentration of an ion in a solution.

Aug 24, 2017 · An osmole is the number of moles in a compound that contributes to the osmotic pressure. The main difference between osmolarity and osmolality is that osmolarity is a measure considering the volume of a solution whereas osmolality is measured considering the mass of …

The unit of measurement of osmolality is the osmole. The term relates to osmosis and is typically used for osmotically active solutions. The osmolality of a solution is the number of osmoles of solute per kilogram of solvent.

Jun 27, 2015 · An osmole is the amount of substance which must be dissolved in order to produce an Avogadro's number of particles (6.0221 × 10 23). Both osmolality and osmolarity are colligative properties of the solution, i.e. they depend on the number of particles dissociated in the solution, but not on the characteristics of the particles themselves.

Nov 1, 2010 · An osmole is 1 mole of any fully dissociated substance dissolved in water. Osmolality is the concentration of osmoles in a mass of solvent. In biologic systems, osmolality is expressed as mOsm/kg of water and can be measured using an osmometer.

Nov 10, 2024 · osmole (plural osmoles) A unit of measurement, a mole of an osmotically active compound
