Calculate stock volume for a target concentration and final volume.
A clear answer. Here’s how.
Uses C₁V₁=C₂V₂ with the same solute and concentration basis. Stock volume = target concentration × final volume ÷ stock concentration. Target cannot exceed stock concentration. The nominal solvent difference assumes additive volumes; this is arithmetic, not a preparation protocol.

Worked example
A fixed demonstration, separate from the values you enter above.
- Stock concentration (mol/L)
- 1
- Target concentration (mol/L)
- 0.1
- Final solution volume (mL)
- 100
Example result
- Stock solution volume (mL)
- 10
- Nominal solvent volume difference (mL)
- 90
- Final solution volume (mL)
- 100
