Keep the units in the calculation.

Calculate mass concentration, amount concentration, and a laboratory dilution. Every result shows the converted inputs and equation.

State the assumptions first.

Use the final solution volume. These calculations assume the entered solute amount is correct, the material is fully dissolved and stable, and no material is lost. They do not verify identity, purity, solubility, sterility, or measurement uncertainty. Enter a decimal point; scientific notation such as 1e-3 is accepted.

Mass and amount concentration

Leaving molar mass blank returns mass concentration only. No molecular weight is inferred from a compound name.

Laboratory dilution

C₁V₁ = C₂V₂. Use the same solute and concentration basis for stock and target.
