Molarity and Dilution (C1V1=C2V2)
Solve for the missing fourth from any three of stock concentration, stock volume, final concentration, final volume.
Example
You enter
- C1 (M, leave 0 to solve) 1
- C2 (M, leave 0 to solve) 0.1
- V2 (L, leave 0 to solve) 0.05
You get
- Stock volume V1 (L) 0.005
- Final volume V2 (L) 0.05
- Diluent volume 0.045
Details, formula, and sources
C1 * V1 = C2 * V2. Solve for the missing fourth.

Verify protocol against your lab's SOP before pipetting. A miscalculated dilution can ruin a run or a sample.
