gdm^-3/gmol^-1
g/g=1 dm^-3/1=dm^3 1/mol^-1=mol^1 1 x dm^-3 x mol^1 mol/dm^3
To convert from g/dm^3 to mol/dm^3 you have to divide g/dm^3 by g/mol or the molecular mass.
To convert from g/dm³ to mol/dm³, divide the concentration in g/dm³ by the molar mass of the solute in g/mol. This will give you the concentration in mol/dm³. Remember to always use the correct molar mass for your specific solute during the conversion.
