Frequently asked questions
- How is molality different from molarity?
- Molarity (mol/L) is moles per litre of solution; molality (mol/kg) is moles per kilogram of solvent. Molality is temperature-independent because mass doesn't change with temperature, while volume does.
- What are colligative properties?
- Properties that depend only on the number of solute particles, not their identity: boiling-point elevation, freezing-point depression, osmotic pressure, vapour pressure lowering. Note: the shown Kb/Kf values assume non-electrolyte solutes.
