Concentration measured by the number of moles of solute per kilogram of solvent
In chemistry, concentration is the measure of how much of a given substance there is mixed with another substance. This can apply to any sort of chemical mixture, but most frequently the concept is limited to homogeneous solutions, where it refers to the amount of solute in the solvent.
Molality is the number of moles of solute dissolved in one kilogram of solvent. Notice the two key differences between molarity and molality. Molality uses mass rather than volume and uses solvent instead of solution. ...
Molality (of a solute) = mol/kg (category unit)
Molality is a section of thoroughness used to bulk the thoroughness of a solute in a singular kilogram of well-off substance.
The number of grammolecules weight of a solute per kg of solvent.
