molality. is used in place of molarity. Molality (m) is the number of moles of solute. per 1 kilogram (or 1000 grams of solvent. For example, a two molal (2 m) solution contains two. moles of solute dissolved in 1 kilogram of solvent. Example 1. Calculate the molality of a solution prepared by dissolving 36.0 g of glucose, C6H12O6, in 400.0 g ...

Molality is greater than molarity because the volume increases when the solute dissolves in water so now the volume of the solution is greater than the mass of the water. If there is very little solute (dilute solution) then it is a good assumption that the volume does not change and molarity equals molality.

The molarity of a solution is often used as a conversion factor between moles of solute and volume of solution: it is a “molar density”. Interpreting molar solutions: A 1.0 M solution would contain 1.0 moles of solute per liter. Remember, a solution is uniform, therefore, the ratio of solute to solution would be the same regardless of the ...
