Concentration measured by the number of moles of solute per liter of solution


Noun: molality

|mow'la-li-tee|

Concentration measured by the number of moles of solute per kilogram of solvent

=molal concentration

Answer 2

Difference Between

Molarity & Molality

$\mathcal{\underline{MOLARITY }}$

:- it is the ratio of no. of moles of molecules is to the volume of solutions (in litres)

or no. of moles of molecules in one litre of solution

$\mathcal{\underline{ MOLALITY }}$

:- it is the ratio of no. of moles of molecules is to the mass of solution (in kg)

or no. of moles of molecules in one kilograms of solution
