Frequently asked questions
- What is the difference between molarity and molality?
- Molarity (M) is moles per litre of solution; molality (m) is moles per kilogram of solvent. Molality doesn't change with temperature; molarity can because liquids expand.
- How do I make a 1 M NaCl solution?
- Dissolve 58.44 g of NaCl (molar mass ≈ 58.44 g/mol) in enough water to make exactly 1 litre of solution.
