Question

write the different between molarity and molality of solution ​

Answer 1

Explanation:

An important distinction between molality and molarity is the difference between a solution and a solvent.

Molarity is the ratio of the moles of a solute to the total liters of a solution.

Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent

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 is

m = Numbers of moles of solute/Mass of solvent in kgs

m = (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.
