Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.
. This contrasts with the definition of molarity which is based on a specified volume of solution. 1 mole of a pure substance has a mass equal to its molecular mass 1 expressed in grams. This is known as the molar mass M and has the units g mol-1 gmol grams per mole of substance The relationship between molar mass mass and moles can be expressed as a mathematical equation as shown below.
A commonly used unit for molality in chemistry is molkgA solution of concentration 1 molkg is also sometimes denoted as 1 molalThe unit molkg requires that.
