Answer:

#"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"#.........
