Equation
M₁V₁ = M₂V₂
Variables
- M₁ = initial concentration
- V₁ = initial volume
- M₂ = final concentration
- V₂ = final volume
Units
- Concentration: moles per liter (mol/L or M)
- Volume: liters (L)
When To Use This Formula
Use this formula when calculating how the concentration of a solution changes after adding solvent while the amount of solute remains constant.
Rearranged Equations
- M₂ = (M₁ × V₁) / V₂
- V₂ = (M₁ × V₁) / M₂
- M₁ = (M₂ × V₂) / V₁
- V₁ = (M₂ × V₂) / M₁
How to Use This Formula
- Identify the known values from the problem statement.
- Convert all values into compatible units.
- Substitute the values into the equation and calculate the result.
- Check that the final answer has the correct unit and meaning.
