Concentration Calculator

The current version focuses on three common wet-lab tasks:

• Dilution: calculate stock volume and diluent volume from stock concentration, target concentration, and final volume.
• Preparation: calculate how much solid reagent to weigh for a target solution.
• Conversion: convert between molarity and mass concentration, with molecular weight used when crossing types.

Recommended usage:

• Use Dilution for routine stock-to-working-solution workflows.
• Use Preparation when making a solution from a solid reagent.
• Use Conversion when you already know one concentration expression and need another.

Current scope:

• Preparation is designed for solid reagents first.
• More complex liquid-preparation cases that depend on density or purity are not included yet.
• Molecular weight is required when converting between molarity and mass concentration.
