Question

Explain MOLALITY.......​

Answer 1

Molality is a measure of number of moles of solute present in 1 kg of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg. A solution of concentration 1 mol/kg is also sometimes denoted as 1 molal.

Answer 2

Answer:

Molality is one of the important properties of solutions. It is used to express the concentration of a solute in a solution and mostly depends on the mass of the solvent. Molality is also sometimes referred to as molal concentration. It is usually denoted by the letter “m”.

The concept of molality was basically framed as a relation to molarity which is described as the molar concentration of a solution. The use of this property was first recorded in the publication authored by G. N. Lewis and M. Randall in the year 1923. The topic was covered in the book titled “Thermodynamics and the Free Energies of Chemical Substances.”
