solution will change as solute is added. Solubility units that incorporate units of solution include grams of solute per 100 grams of solution or grams of solute per liter of solution. Another way to express solubility is in moles of solute per liter of solution; this ratio is called "...
One millimolar (1 mM) is equal to one-thousandth of a mole per liter (1/1000 mol/L). If a solution has a 5 millimolar (5 mM) concentration for a particular substance, it means that there are 5 millimoles of that substance dissolved in one liter of the solution. Popular Questions ...
