2019-11-21 · 0.5 M of NaCl solution means 0.5 mol of NaCl in a litre of the solution. As the value of molar concentration increases, the amount of the solute per litre also increases. For example, 1.0 M of NaCl solution will have a more amount of NaCl than 0.5 M of NaCl per litre of solution. The figure below depicts the same.
Concentration = 55.56 mol / 1 dm 3. Concentration of water = 55.56 mol dm-3. How to calculate concentration in mol dm-3? From mol dm-3 we know, we have to calculate the molarity.
