The number of moles of solute present in 1 kg of a solvent is called its molality.

The number of moles of solute present in 1 litre of a solution is called its molarity.

Actually, Molarity(M) is defined as the no of moles of solute per 1 lit solvent and the Molality(m) is defined as the no of moles of solute per 1 kg solvent.

solute eq.wt present in1litre(solvent)=1normal(N )
solute m.w present in 1Kg(solvent) =1molal(m)
solute m.w present in 1litre(solvent)=1molar(M )

Its molarity not molality because this two words are confusing reason being that in chemistry under this chapter theres nothing like molality.

Molality is the amount of substance of a solute present per unit volume of solvent;the volume measured is that of solvent, Not the solution.

1kg is equivalent to 1litre. 1kg means 1000g and 1litre also the same mean 1000g but kg use for solid things and litre for liquid things.

It is Molarity. It is a unit of the concentration measuring the number of moles of a solute per liter of solution.

In morality number of mole present in kg solution but in morality no of mole present in one kg of solvent.

I think better answer is, Molality is defined as the ratio of on of 1gram of solute in 1kg of solvent.

I'm trying to review for mid terms and I still can't understand how to do moles. Even in the comments.
