Question

explain the following concentration term.
Molarity.
molality.
mole fraction. ​

Answer 1

$\huge\underline\bold\color{red}\mathfrak{Answer}$

Molarity = It is the no.of moles of solute dissolved in one litre of solution.

Molality = It is the no.of moles of solute dissolved in 1 kg of solvent.

Mole fraction = It is the ratio of no. of moles of one component to the total no. of moles of the solution.

❣️Hope it helps❣️

Answer 2

Molarity :- Number of Moles of solute dissolved per liter of solution is known as molarity .    

  e.g. M = n/v

 Unit :- mol / lit.

Molality :- Number of moles of solute dissolved per Kg of Solvent is known as molality .

e.g. m = n/weight of solvent in Kg

 Unit :- mol/Kg

Mole Fraction :-   The number of moles of a component divided by the total number of moles of a solution gives the Mole fraction .

  Unit :- This is unitless
