How to use
Molarity
Molarity is moles of solute per liter of solution:
$$M = \frac{n}{V}$$
- Use when the solute is dissolved and you care about volume of solution (not solvent mass).
- SI-friendly: keep $V$ in liters for mol/L.
When to use
- Preparing stock solutions from a known amount of solute.
- Comparing solution strength before a titration or dilution.
