Chemistry
Dilution Formula
Calculate concentrations during dilution.
M₁V₁ = M₂V₂
Formula Explanation
For dilution with solvent only, the amount of dissolved solute remains constant.
Variables Explained
M₁, V₁ = Initial concentration and volume; M₂, V₂ = Final concentration and volume.
Solved Example
What final volume gives 0.5 M from 100 mL of 2 M solution?
V₂ = (2 × 100) / 0.5 = 400 mL.
