The unit is mol/kg; molality is not a unit, it is a measure of concentration.

This is the amount (concentration) of the solute in the solvent.

Molality measure the concentration of a solute.


(chemistry) the concentration of a substance in solution, expressed as the number moles of solute per kilogram of solventmolality = moles of solute / kg of solvent


The amount of solute dissolved in a given amount of solvent is the concentration of the solution. Concentration is measured in moldm-3, mgdm-3. Concentration can be changed with the temperature.


The concentration of the solute is higher than the concentration of the solvent.


These two variables have an inverse relationship. That is, the higher the solvent concentration, the lower the solute concentration. Similarly, the lower the solvent concentration, the higher the solute concentration.


This concentration is called molality (now an obsolete term).



Molality is the number of moles of solute dissolved in one kilogram of a solvent. It is found by dividing the number of moles of solute by the weight of solvent measured in kilograms.


Usually the amount of solute in a solvent is measured by concentration, that is, how many grams of the solute is in one liter of solvent. This is called molarity or M.


No. dilution is the addition of solvent to decrease the concentration of a solute.


This kind of concentration is known as The units are m (not capitalized) Do not confuse this with molarity (M) which is moles of solute per Liter of solution.


Remember the distinction between concentration and solubility. Concentration is measured in grams of solute per 100 mL of solution (g/100 mL solution), but solubility is measured in grams of solute per 100 mL of solvent(g/100 mL solvent). Different solutes have different solubility's, as Table 1 shows.


Solute is the substance which dissolves in the solvent. Its concentration is always less than that of solvent.


This is the concentration of the solute in the solution.


Solute concentration is the amount of solute that is dissolved in a solvent. This can be calculated by either mass or volume.


concentration= solvent times solute


In general the amount of a solute (the smaller component) in a solvent (the larger component). The higher the concentration the more solute relative to solvent. This can be expressed many ways such as molarity (moles per liter), molalitity (moles per kilogram of solvent), weight percent, volume percent, etc.


A solute dissolves in a solvent, resulting in a solution. The concentration of a solution is the amount of solute dissolved in a fixed amount of the solution.


This information is about the concentration of the solute in the solvent.


It is the amount of solute dissolved from a solvent in a solution



Dilute solution: low concentration of the solute in the solvent Concentrated solution: high concentration of the solute in the solvent


Solutions are mixtures of solutes and solvents. A solute is mixed into a solvent. A solvent has a greater concentration than the solute. For example: Salt water is a solution, where the water is the solvent(higher concentration), and the salt is the solute(lower concentration).
