differentiate between molarity and molality.
Answers
Answer:
Both molarity and molality are measures of a chemical solution's concentration. ... The molality describes the moles of a solute in relation to the mass of a solvent, while the molarity is concerned with the moles of a solute in relation to the volume of a solution.
Answer:
Difference between molarity and molality
Explanation:
Molarity :-
Molarity of a given solution is defined as the total number of moles of solute per litre of solution.
Mathematical expression is M = number of moles of the solute /Volume of solution given in terms of litres.
Depends on volume of the whole solution.
Unit sign expressed as (M).
Molarity has a unit of moles/liter.

Molality :-
Molality is defined as the total moles of a solute contained in a kilogram of a solvent.
Mathematical expression is
m = Numbers of moles of solute/Mass of solvent in kgs
m = (g ✕ 1000)/(W ✕ m).
Depends on the mass of the solvent.
Unit sign expressed as (m).
Molality has units of moles/kg.
