✦ Synopsis

The preparation of high molar concentrations of many solutes can often be very timeconsuming owing to the substantial volume, and sometimes temperature, changes which occur as the solute dissolves. By contrast, the preparation of solutions of a given molality is much simpler since all that is required is to mix known weights of the solute and solvent. This paper describes a simple method and a computer program (MOLAL) for preparing known volumes of a given molarity for twenty commonly-used solutes, by means of calculated molalities: the density of the resulting solutions is also given.
