1)molality:-
when one mole of the solute is dissolve in 1000g of the solvent , it is called 1 molal solution. thus molality is the no.of moles of the solute present in 1000g of the solvent
it is denoted by 'm'
2)molarity:-
(M) when one mole of the solute is present in one litre of solution , it is called molar solution
molarity is the no.of moles of the solute present per litre of the solution .
it ix denoted by the letter M
3)mass percentage:-
=mass of solute in grams/volume of solution in ml ×100
,4) mole fraction:-
it is the ratio of the no.of moles of solute (n1) or solvent (n2) to the total no.of moles in the solution.

Bonjour!
* Mole fraction:-
It is the ratio of number of particular component to the total number of moles in the solution.
The mole fraction of all the components in solution is always equal to one.
* Molality:-
It is defined as number of moles of solute present in 1 kg of solvent.
Unit: mol kg-¹(molal) ---› 'm'
Molality of a solution does not change with temperature since mass remains unaffected with change in temperature.
* Molarity:-
It is defined as number of solute dissolved in 1 litre of solution.
Unit: mol/litre or mol L-¹ or M(Molar)
Molarity of a solution depends upon temperature because volume of a solution is temperature dependent.
* Mass percentage:-
It is the percentage of solute present in a solution.
Mass percentage is independent of temperature.
Hope this helps...:)
