Dilution Equation

M₁V₁ = M₂V₂
M₁ = initial molarity, V₁ = initial volume
M₂ = final molarity, V₂ = final volume
Dilution means adding solvent → concentration decreases.
Volume units must match on both sides (both mL or both L).

Tips

The concentrated solution (M₁) always has higher molarity.
V₂ is always larger than V₁ (you're adding solvent).
Rearrange to solve: M₂ = M₁V₁/V₂, V₁ = M₂V₂/M₁, etc.

Dilution (M₁V₁ = M₂V₂)
