During the preparation of the electrolytes in electrochemistry, you can use either the molar concentration or the mass concentration (also designated wt%). This Demonstration will enable you to quickly convert between the molar concentration and the mass concentration. For example, you can quickly estimate the molar concentration of a 3 wt% NaCl solution or the mass concentration of a 0.5 M solution.
