A solute is a chemical component of a mixture that is dissolved in the solvent. An example of a solute is sucrose when it has been dissolved into water to make sugar water. When calculating molarity, the amount of solute is measured in moles (mol).

WebThus, concentration or molarity inside the plant tissue was also = 0.28 moles dm-3. Since the solution is carrying 2 ions i.e. Na+ and Cl-, we will multiply the value of molarity by 2. Osmolarity = 0.28 × 2 = 0.56 osmoles dm-3. (ii) Identify which part of the graph represents samples measured in a hypotonic solution. Web22 jan. 2024 · Molarity – number of solute particles in a solution. The difference between osmolarity and molarity is explained by the van’t Hoff factor – the number of moles (not the mass or weight) of dissociated solute particles (ions) in a solute. For example, a 1 mol/L glucose solution does not dissociate; the van’t Hoff factor is, therefore, one.

WebThe concentration of a solution is a measure of the relative amount of solute in a given amount of solution. Concentrations may be measured using various units, with one very useful unit being Molarity.
