What is Molarity?
Molarity (M) is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute per liter of solution.
Key Formulas
Molarity (M) = moles of solute ÷ liters of solution
Moles = Molarity × Volume (L)
Volume (L) = Moles ÷ Molarity
Mass (g) = Moles × Molar Mass (g/mol)

Important Notes
- Always use consistent units (convert mL to L when necessary).
- Molarity is temperature-dependent because volume changes with temperature.
- For very dilute solutions, consider using molality instead.
