Molality/PPM Worksheet. molality (m) moles of solute / kg of solvent . Another way to calculate concentration. Notice the difference in the denominator compared to molarity. (L vs kg; solution vs. solvent) Molality is independent of temperature so it is used for calculating boiling point elevation.
