conversion ion concentration from gram/litre to moles ions

[Rafah]

i need to convert the concentration of different metal ions released in an aqueus solution, i've them in g/L so i want to convert the units to moles to be able adding all the ions' concentrations to have the total ions released in the solution

Divide the weight in grams by "molecular" weight to get moles. For the metal ions, this is just the atomic weight, for other things, you may have to add up the atomic weights of the elements (and number of atoms) that make up the chemical formula. The result will be moles/liter, often called molarity.
