Lab experiments often require list of chemical solutions in their procedure, which need to be purchased or prepared. The most common solutions’ unit is molarity (M). The molarity of a solution is defined as the number of moles of solute per one liter of solution. In case of a molarity solutions, to prepare a solution that contains a specified concentration of a substance, it is necessary to dissolve the desired number of moles of solute in enough solvent to give the desired final volume of solution. This may involve weighing a precise amount of a dry material, i.e. dissolving a known mass of solute in a solvent and diluting to a desired final volume or measuring a precise amount of liquid, i.e. diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume.
