Question

what is defference between molarity and molality​

Answer 1

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 2

Answer:

Molarity

Molality

Molarity of a given solution is defined as the total number of moles of solute per litre of solution.

Molality is defined as the total moles of a solute contained in a kilogram of a solvent.

Mathematical expression is M = number of moles of the solute /Volume of solution given in terms of litres.

Mathematical expression ism = Numbers of moles of solute/Mass of solvent in kgsm = (g ✕ 1000)/(W ✕ m).

Depends on volume of the whole solution.

Depends on the mass of the solvent.

Unit sign expressed as (M).

Unit sign expressed as (m).

Molarity has a unit of moles/liter.

Molality has units of moles/kg.
