Molality: Is also known as molal

Molality is also known as molal concentration. It is a measure of solute concentration in a solution. The solution is composed of two components; solute and solvent. There are many different ways to express the concentration of solutions like molarity, molality , normality, formality, volume percentage, weight percentage and part per million. The term needs to calculate the mass of the solvent and moles of solute. Molality is the term used to express the concentration of the solution. The concentration of a solution is defined as the measure of the quantity of one substance when it is mixed with another substance. Let's learn about Molality in detail, including its definition, SI unit formula, and solved examples. Definition of Molality The molality of a solution is defined as the number of moles of a solute per kilogram of solvent. It depends on the mass of the solvent. It is also referred to as ... Molality (m) is defined as the number of moles of the solute per kilogram (kg) of the solvent. It is expressed as: Molality (m) = Moles of solute Mass of solvent in Kg Therefore, the unit of molality is mole per kg (mol kg −1). If n B moles of solute are dissolved in W grams of solvent, then Molality = n B W × 1 0 0 0 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.
