2.02g of KNO3 ( Mz=101) is dissolved in sufficient water to prepare 0,500 dm3 of solution. What is the concentration of this solution in mol dm?

  Bob Pursley gave you the information in your previous post. M = moles/L. So I would change 2.02 g KNO3 to moles and divide that by the volume in dm^3. Again, I must ask just what mol dm means?
