Osmotic concentration - Wikipedia
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).
Osmolarity - The Definitive Guide - Biology Dictionary
2021年1月22日 · 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.
Osmolarity and Osmolality in Chemistry - ThoughtCo
2019年5月9日 · 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 …
Osmole | definition of osmole by Medical dictionary
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.
Difference Between Osmolarity and Osmolality
2017年8月24日 · 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 …
Osmolarity and Osmolality - an overview | ScienceDirect Topics
2010年11月1日 · 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.
Osmolarity, osmolality, tonicity, and the reflection coefficient
2015年6月27日 · 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.
Osmolarity | Definition, Formula & Osmolarity vs. Osmolality
2019年5月24日 · An osmole (Osmol) is basically 1 mol particles that contribute to generating Osmotic Pressure of a solution. For example, when NaCl dissolves in water it completely dissociates in water and forms Na + ions and Cl – ions.

Basic concepts and practical equations on osmolality ... - PubMed
Osmole is unit of the amount of substance, one mole of nonionized impermeant solute is one osmole. Assuming an ideal solution, osmotic pressure (π) in mmHg is 19.3 times the osmolarity. Osmolarity is defined as the number of milliosmoles of the solutes per liter of solution.
