Did you know?
WebMolarity is the ratio of a solvent’s moles to a solution’s total litres. Both the solute and the solvent are part of the solution. Molality, on the other hand, is the ratio of the solute moles to the solvent kilogrammes. Mole fraction is the mole of a constituent divided by the total mole of all constituents in a mixture. WebHowever, the molality definition does not have a volume in it and so is independent of any temperature changes. This will make molality a very useful concentration unit in the area of colligative properties. Lastly, it is very common for students to confuse the two definitions of molarity and molality. The words differ by only one letter and ...
