"Molality, molarity, parts per million...........??"

Explanation:

"Molality"="Moles of solute"/"Kilograms of solvent"

"Molarity"="Moles of solute"/"Litres of solution"

"parts per million"="milligrams of solute"/"Litres of solution"

As to which term you use that is precisely dependent on the chemistry you do..... Synthetic chemists would tend to use "molarity" and "molality". Analytical and physical chemists would tend to use "ppm".........
